When federal prosecutors add a gun charge in San Antonio, TX, the stakes can climb fast. A case that was already serious may suddenly carry mandatory incarceration, consecutive sentencing, property forfeiture, and permanent limits on firearm ownership. These prosecutions are often built by the ATF and the U.S. Attorney’s Office alongside allegations of federal drug crimes, conspiracy, robbery, or violent conduct.
The gun does not have to be used in the way most people imagine. Federal charges may grow out of constructive possession, a straw purchase, false statements to a dealer, access to an unregistered weapon, or a firearm found near alleged criminal activity. In some cases, the firearm allegation is what turns a difficult prosecution into one carrying years of additional prison exposure.

What Makes a Gun Charge Federal?
The line between a state gun case and a federal prosecution is not always obvious. A case may cross that line because of the weapon involved, the accused person’s legal status, the location of the alleged conduct, or a claimed connection to interstate commerce. Violations of the Gun Control Act, the National Firearms Act, or another federal statute may give the U.S. government authority to prosecute. Local agencies can also refer cases upward when they want federal prosecutors to pursue harsher consequences.
A gun case may draw federal attention when:
- A prohibited person allegedly possessed a gun or ammunition
- The weapon allegedly traveled in or affected interstate or foreign commerce
- The firearm was supposedly used, carried, or kept in connection with another federal crime
- The investigation concerns illegal sales, straw buyers, trafficking networks, or cross-border smuggling
- The gun falls into a specially regulated category under federal law
- Authorities discover a defaced or missing serial number
- The incident happened on federal property or during another federal investigation
- The government believes the weapon played a role in organized criminal activity
The first sign of trouble may come late in the investigation. Agents may already have traced the gun, interviewed witnesses, reviewed online activity, pulled phone data, and gathered physical evidence before the accused knows federal prosecutors are involved.
How to Protect Yourself During an ATF Investigation in San Antonio, TX
An arrest is not the starting line of a federal gun case. ATF agents may already have reviewed records, interviewed witnesses, traced firearms, and gathered digital evidence before they ever contact you. The decisions you make at that point can either protect your position or hand the government more ammunition.
Take the following steps as soon as you suspect a federal firearms investigation:
- Exercise your right to remain silent. You do not need to answer questions from ATF agents, task force officers, or federal prosecutors without a federal firearms attorney in San Antonio, TX present. What feels like harmless background information can become evidence.
- Do not give blanket consent. If law enforcement has a valid warrant, let your lawyer challenge it later. Do not voluntarily open additional devices, accounts, rooms, safes, or vehicles unless counsel advises you to do so.
- Do not erase the paper trail. Keep purchase forms, receipts, emails, photographs, texts, and other records intact. Destroying or altering evidence can make the situation far worse.
- Say less to everyone else, too. Friends, relatives, coworkers, and alleged associates can be interviewed or subpoenaed. Social media posts and private messages are not safe places to explain the case.
- Contact a federal criminal defense lawyer in San Antonio, TX immediately. The earlier your attorney enters the case, the sooner they can protect your rights, identify weak points in the investigation, and keep you from stepping into traps the government has already set.
Federal Weapons Charges You May Face in San Antonio, TX
Felon in Possession of a Firearm
A person may face a federal gun charge based on their legal status rather than how the firearm was allegedly used. Under 18 U.S.C. § 922(g), firearm and ammunition possession is prohibited for several categories of restricted persons.
A person may be legally barred from possessing a gun or ammunition because of:
- People convicted of crimes punishable by more than one year in prison
- Fugitives from justice
- Unlawful users of controlled substances
- Certain people subject to domestic violence restraining orders
- People convicted of qualifying domestic violence offenses
- Certain noncitizens and people dishonorably discharged from the military
The prosecution must generally connect two pieces of the puzzle: the accused knowingly possessed the gun or ammunition, and they knew about the legal status that made that possession prohibited.
Federal firearm possession is commonly divided into two categories:
- Actual possession: The firearm was allegedly found directly on the person.
- Constructive possession: The person allegedly knew the firearm was present and had the ability and intention to control it.
Constructive possession can become the fault line of the case when a firearm is recovered from a place multiple people could access, such as a shared residence, borrowed car, hotel room, or common storage area.
Using, Carrying, or Possessing a Gun Under 18 U.S.C. § 924(c)
18 U.S.C. § 924(c) makes it a separate federal offense to use or carry a firearm during and in relation to a qualifying crime of violence or drug trafficking crime, or to possess one in furtherance of such a crime.
The statute carries mandatory minimum prison terms that generally run back-to-back with the sentence imposed for the related offense:
- Possession, use, or carrying: A minimum of five years
- Brandishing: A minimum of seven years
- Discharging the firearm: A minimum of 10 years
- Machine guns, silencers, or destructive devices: Potentially much higher mandatory minimums
The prosecution may describe a firearm as a tool of the alleged offense even when it stayed hidden or untouched. That argument commonly relies on its location near:
- Narcotics
- Money
- Packaging equipment
- Sales or distribution records
- Anything else agents label as evidence of trafficking
Proximity alone may not tell the whole story. The defense may argue that the firearm belonged to someone else, was inaccessible, was present for an unrelated lawful reason, or did nothing to promote the alleged offense.
Buying a Firearm for Another Person
Federal prosecutors may allege a straw purchase when the person completing the transaction is accused of buying the gun on behalf of someone else. The case may involve the “actual transferee/buyer” question on ATF Form 4473, along with charges under 18 U.S.C. § 932.
Questions that may determine whether the transaction was lawful include:
- Payment apps, cash withdrawals, or reimbursements
- Who researched, requested, or picked out the firearm
- The buyer’s plan before entering the store
- Whether the gun was genuinely purchased as a gift
- Whether the eventual recipient was prohibited or intended to use the firearm unlawfully
These cases leave a digital and documentary trail. Prosecutors may rely on Form 4473, receipts, cash transfers, text conversations, security footage, firearm tracing records, and interview statements to argue who the real buyer was.
Transporting or Transferring Firearms Unlawfully
A gun sale does not need to happen in a back alley to draw a federal trafficking charge. Section 933 applies to certain firearm transfers, receipts, and transportation when the accused knew or had reason to believe the weapons would end up in illegal hands.
Federal agents may characterize firearms as trafficked when they were allegedly:
- Purchased using another person’s name or eligibility
- Moved from a state with looser availability into another jurisdiction
- Sold to alleged gang members, traffickers, or violent offenders
- Acquired through coordinated straw purchase schemes
- Bought and flipped without a required dealer’s license
- Concealed or transported for unlawful export
When Private Gun Sales Become Federal Charges
Federal law generally requires a person who is engaged in the business of dealing firearms to obtain a federal firearms license. An occasional private sale does not automatically make someone a firearms dealer.
To argue that someone was acting as a dealer, the government may look at:
- Repeated buying and reselling rather than isolated transfers
- Short turnaround times between acquisition and sale
- Advertising guns to members of the public
- Negotiations, payment histories, and delivery arrangements
- A business or profit-making purpose
- A stock of firearms maintained for resale
Federal Charges for False Firearm Purchase Statements
Under 18 U.S.C. § 922(a)(6), it is illegal to knowingly make a false statement to a federally licensed firearms dealer when that statement is material to the legality of the sale.
Federal investigators may focus on statements about:
- Who was actually purchasing the gun
- Whether the buyer had a disqualifying criminal record
- Current or recent controlled-substance use
- Domestic violence convictions or restraining orders
- Immigration classification or citizenship
- Where the person lived or whether the identification was accurate
The government must do more than point to an inaccurate box on a form. The defense may dispute whether the response was truly false, whether the accused understood it was wrong, or whether it made any legal difference to the sale.
Defaced or Obliterated Firearm Serial Numbers
Federal law restricts the knowing possession, receipt, or transportation of certain firearms whose serial numbers have been changed, removed, or made unreadable. The relevant regulation appears at 27 CFR § 478.34.
The serial number itself is only part of the case. Other issues include:
- Whether the accused knew the serial number had been altered
- Whether the markings meet the statutory definition
- Whether forensic testing can recover the original number
- Whether the government can connect the accused to the firearm
A firearm with a removed or changed serial number may add another rung to the sentencing ladder through a federal guideline enhancement.
Homemade and Privately Assembled Firearms
The label “ghost gun” can make a case sound simpler than it is. A privately assembled firearm may be lawful in some circumstances, while its possession, manufacture, sale, or markings may create federal exposure in others.
Federal agents may look at the entire life of the firearm, including:
- Who assembled and ultimately possessed it
- The parts, process, and configuration used to make it
- Whether it remained for personal use or was transferred to someone else
- Whether multiple weapons were built for sale
- Whether federal marking requirements applied
- Whether the firearm appeared in another criminal investigation
Sentencing enhancements may also apply in some cases involving firearms without required serial numbers.
Federal National Firearms Act Charges
A firearm that is lawful in one configuration can fall under much stricter rules after certain modifications. The National Firearms Act governs several categories of weapons and devices through registration, taxation, transfer, and manufacturing requirements.
The Act covers categories such as:
- Machine guns
- Shortened rifles
- Shortened shotguns
- Suppressors, including devices commonly called silencers
- Certain bombs, explosives, and destructive devices
- Unusual or concealed weapons classified as “any other weapon”
Federal agents may bring NFA charges when they believe a regulated item was never registered, was made or transferred without approval, or had required markings removed. The potential consequences include substantial fines, forfeiture, and up to a decade in federal custody.
Federal Firearm Sentences in San Antonio, TX
There is no universal sentence for a federal gun conviction. Prison exposure can change based on the charge, the firearm involved, prior convictions, any connection to another alleged crime, and the calculation required by the federal sentencing guidelines.
| Federal Gun Offense | Potential Prison Exposure |
|---|---|
| Unlawful firearm possession by a prohibited person under § 922(g) | Up to 15 years in many cases, with a 15-year mandatory floor when ACCA applies |
| A § 924(c) firearm charge tied to drug trafficking or a qualifying violent offense | Mandatory minimum of five years, seven years if brandished, or 10 years if discharged, generally served consecutively |
| Straw purchasing under 18 U.S.C. § 932 | A maximum of 15 years in ordinary cases, potentially rising to 25 years when the weapon is believed destined for certain serious offenses |
| Firearms trafficking under 18 U.S.C. § 933 | Up to 15 years in federal prison |
| Operating as an unlicensed firearms dealer | Generally a five-year maximum term of imprisonment |
| Knowingly providing material false information to a licensed firearm dealer | As much as a decade in federal custody |
| Federal charges involving an altered firearm serial number | A possible five-year sentence plus additional guideline consequences |
| Offenses involving unregistered or unlawfully transferred NFA weapons | Potentially a decade in federal custody, plus monetary penalties and seizure of the firearm |
| Illegal machine gun possession or transfer | A possible 10-year sentence on the machine gun charge alone, with more severe consequences if § 924(c) or another enhancement applies |
The penalties listed above are starting points, not predictions. The sentence in a particular case may rise or fall based on the statute charged, the number and type of weapons, prior convictions, any mandatory minimum, and the calculation required by the federal sentencing guidelines.
Additional penalties and long-term consequences may include:
- Large financial penalties
- A term of federal supervised release following incarceration
- Seizure and forfeiture of guns, ammunition, cash, vehicles, and other alleged proceeds or instrumentalities
- Permanent or long-term restrictions on possessing firearms
- Barriers involving jobs, housing opportunities, and professional credentials
- Removal, inadmissibility, or other immigration problems for noncitizens
A federal sentence is not typically cut short through parole. Although some prisoners can earn good-conduct credit, federal incarceration generally means serving the great majority of the term imposed.
Federal Gun Charges and the ACCA
The Armed Career Criminal Act can turn an already serious prohibited-person case into one with a 15-year mandatory minimum. The law is often referred to by its initials, ACCA.
ACCA may apply to a person convicted under 18 U.S.C. § 922(g) who has three qualifying prior convictions involving violent felonies, serious drug crimes, or some combination of the two, so long as the offenses occurred on different occasions.
Prior convictions do not count merely because prosecutors call them violent or serious. Courts may need to dissect the elements of the earlier statute, examine a limited set of judicial records, and apply federal appellate and Supreme Court decisions that continue to shape ACCA law.
A San Antonio, TX federal firearms attorney may dispute:
- Whether the earlier conviction legally qualifies as a violent felony or serious drug offense
- Whether the permitted court records prove the necessary version of the offense
- Whether the prior crimes were truly committed on separate occasions
- Whether any conviction was overturned, set aside, expunged, or invalidated
- Whether firearm rights or other civil rights were restored
The math is unforgiving: the government needs three qualifying predicates. A successful challenge to even one of them may be the difference between an ordinary § 922(g) sentence and at least 15 years in federal prison.
Federal Guideline Enhancements for Gun Charges
Avoiding a mandatory minimum does not necessarily mean avoiding a lengthy sentence. Federal judges begin by calculating the advisory guideline range, and enhancements can dramatically increase that recommendation.
Guideline enhancements may be tied to claims involving:
- Large numbers of firearms
- Stolen weapons
- Altered or obliterated serial numbers
- Trafficking-related conduct
- Machine guns, silencers, destructive devices, or similar regulated weapons
- Firearm possession connected to another felony
- Reckless endangerment while fleeing
- Acting as an organizer or leader
- Obstruction of justice allegations
Although the guidelines are no longer mandatory, federal judges are still required to calculate and consider them before imposing sentence. An experienced defense attorney may contest proposed enhancements, introduce favorable evidence, request departures or variances, and argue that a lower sentence better satisfies federal sentencing law.
Do You Need a Federal Gun Charges Lawyer?
The best time to hire a federal gun charges attorney is usually before formal charges are filed. If you believe federal agents are investigating you, waiting for an indictment may cost valuable opportunities.
Common signs that federal authorities may be building a case include:
- ATF, FBI, DEA, or task force agents attempt to question you
- Agents execute a search warrant at your home or business
- Someone close to you receives a subpoena
- Law enforcement seizes firearms, phones, computers, or records
- You receive a federal target letter
- A codefendant or alleged associate is arrested
- A state firearm case is dismissed or delayed without explanation
- You learn that federal prosecutors are reviewing your case
The earlier a defense attorney becomes involved, the more options may exist. Depending on the circumstances, counsel can handle communications with investigators, help avoid unnecessary interviews, identify constitutional issues, preserve evidence, assess the strength of the government’s case, and present mitigating information before prosecutors decide whether to seek an indictment.
