3D Printed Guns: What Are They and Are They’re Legal
3D Printed Guns: What Are They and Are They’re Legal

As a Firearms Instructor, Gunsmith and, First Aid Fundamentals Instructor, I’ve watched technology reshape our industry in ways most people never imagined. One of the biggest shifts has been the rise of 3D printed firearms. They generate curiosity, concern, and plenty of misinformation. My goal here is simple: give responsible gun owners a clear, factual understanding of what 3D printed guns are — and what the law actually says about them.
What Exactly Is a 3D Printed Gun?
A 3D printed gun is a firearm — or firearm component — produced using a consumer or industrial 3D printer. These weapons fall under the broader category of Privately Made Firearms (PMFs), meaning they’re built by individuals rather than licensed manufacturers. PMFs can include pistols, rifles, receivers, and even components like frames or conversion devices. Not all PMFs are illegal, and not all require serial numbers, depending on how they’re made and the laws of your state.
Federal Law: What’s Allowed and What Isn’t
At the federal level, the rules are more nuanced than most people think:
✔ You can legally make your own firearm for personal use
There is no federal law banning the creation or possession of a 3D printed gun, as long as you are legally allowed to own a firearm and the weapon complies with federal requirements.
✔ But the firearm must be detectable
Under the Undetectable Firearms Act, all firearms — including 3D printed ones — must contain enough metal to be visible to security screening equipment.
✔ And certain components now fall under ATF regulation
A 2022 ATF rule treats many unfinished frames, receivers, and parts kits as firearms, meaning they may require serialization and background checks.
State Laws: Where Things Get Complicated
This is where responsible gun owners need to pay close attention. States vary widely.
States where manufacturing 3D printed guns is explicitly illegal:
• Delaware
• Hawaii
• Rhode Island
• Washington
States where possessing an unserialized 3D printed firearm is illegal:
• Connecticut
• New York
• Oregon
States considering or expanding restrictions
Recent legislation in states like Colorado and Washington aims to criminalize not just the guns themselves, but also the digital files used to print them — a major shift that affects hobbyists, makers, and gun owners alike.
Digital Files: The New Legal Battleground
One of the most controversial areas isn’t the gun — it’s the code.
Several states have introduced bills targeting the distribution or possession of 3D printable firearm files. Courts have upheld some of these restrictions, such as New Jersey’s limits on who can access printable gun files.
This is a rapidly evolving area of law, and it’s one every responsible gun owner should monitor closely.
My Perspective As a Firearms Instructor, Gunsmith and, First Aid Fundamentals Instructor
At Tactical K Training and Firearms, I emphasize responsibility, legality, and safety above all else. Technology will continue to evolve, and 3D printing isn’t going away. But neither are the legal obligations that come with firearm ownership.
Here’s what I tell my students:
• Know your state laws — they may differ drastically from federal rules.
• Stay updated — legislation around 3D printed guns is changing fast.
• When in doubt, ask — ignorance of the law is never a defense.
• Focus on safety and traceability — a firearm you can’t legally possess or transport is a liability, not a tool.
Kielma’s Parting Shot
3D printed guns can be legal — but only under the right conditions. Federal law allows personal manufacture, but state laws may prohibit it entirely or restrict possession of unserialized firearms. And the legal fight over digital files is intensifying.
As responsible gun owners, our job is to stay informed, stay compliant, and stay safe.

Being Prepared for the 2026 Hurricane Season By Gregory Kielma, Tactical K Training & Firearms The 2026 Hurricane Season is shaping up to be another year where preparation isn’t optional it’s essential. Florida has seen record heat, rising insurance pressures, rapid population growth, and increasingly unpredictable storm behavior. None of that is meant to create fear. It’s meant to reinforce a simple truth: preparedness gives you control, confidence, and options when the weather turns. Whether you’re protecting a home, a business, or a family, the goal is the same build layers of readiness before the first storm forms. Start With Awareness and a Plan Storms don’t give you time to “figure it out later.” Your plan should be written, practiced, and known by everyone in the household or workplace. Key elements of a solid plan: Where will you go if evacuation becomes necessary Multiple routes out of your area A communication plan if cell networks fail A designated out‑of‑state contact A plan for pets, elderly family members, and anyone with medical needs For businesses, include: Who secures the building Who handles digital backups Who communicates closures and reopening A plan removes panic. It replaces it with action. Strengthen Your Home or Business Before the First Storm Florida structures take a beating every year. Small improvements now prevent major losses later. Exterior protection: Inspect your roof for loose shingles or soft spots Clear gutters and drainage paths Trim trees and remove dead limbs Install or test shutters Reinforce garage doors—one of the most common failure points Interior protection: Surge protection for critical electronics Elevate valuables and important documents Know how to shut off water, power, and gas If you own a business, walk your property as if you were a storm: What can break? What can blow away? What can flood? Fix those points now. Build a Realistic, Usable Supply Kit For Your Home or Business A hurricane kit isn’t about stockpiling, it’s about independence. After a major storm, help may take hours or days to reach your area. For homes and families: Water: 1 gallon per person per day (minimum 3–7 days) Non‑perishable food Medications and medical supplies Flashlights, headlamps, and batteries Battery bank for phones First aid kit Copies of important documents Cash in small bills Tools, gloves, tarps, duct tape For businesses: Backup power for essential systems Printed employee contact lists Hard copies of insurance documents A plan for securing inventory and equipment Preparedness isn’t about fear it’s about not being dependent on luck. Protect Your Digital Life In 2026, digital readiness is just as important as physical readiness. Back up important files to the cloud and an external drive Photograph your home, business, and valuables for insurance Store digital copies of IDs, insurance policies, and receipts Keep chargers, power banks, and a small solar panel if possible When the power goes out, your digital preparation keeps you moving. Understand Post‑Storm Safety Most injuries happen after the storm, not during it. Be cautious with: Downed power lines Flooded roads Carbon monoxide from generators Unstable structures Contaminated water If you evacuated, don’t rush home. Wait for official clearance. Your safety comes first. Mindset: Prepared, Not Paranoid Preparedness is a discipline, not a reaction. It’s the same mindset we teach in every Tactical K class awareness, planning, and responsible action. A hurricane is a natural event. Your response is a choice. When you prepare early, you protect: Your family Your property Your business Your peace of mind And you set an example for your community. Kielma’s Parting Shot The 2026 Hurricane Season will bring challenges, just like every season. But Floridians are resilient, and preparation is part of our way of life. Start now. Strengthen your home, your business, and your plan. Build your layers of safety before the first storm forms. If you need help building a plan, creating a checklist, or preparing your family or business, Tactical K Training is here to support you with practical, real‑world guidance.
Why You Should Never Travel Through High Water
Convicted Felon Sentenced to 87 Months in Trafficking Nine Firearms, Including to Buyer Who Said He Was ‘At War’ Thursday, April 30, 2026 U.S. Attorney's Office, District of Columbia WASHINGTON - Brandon Smith, 34, a previously convicted felon residing in the District of Columbia, was sentenced today in U.S. District Court to 87 months in prison for conspiring to traffic at least nine firearms to a prohibited buyer over the course of six months, announced U.S. Attorney Jeanine Ferris Pirro. “Brandon Smith was already on supervised probation for a violent felony when he chose to traffic firearms, and he continued even after being told the buyer intended to use them for violence,” said U.S. Attorney Pirro. “Over the course of six months, he arranged the sale of at least nine guns—including one with an obliterated serial number—to a prohibited individual. This was not a momentary lapse in judgment, but a sustained and deliberate effort to arm someone who could not legally possess firearms. My office remains committed to holding accountable those who endanger our communities by trafficking illegal guns.” On Jan. 9, 2026, Smith pleaded guilty before Judge Howell to conspiracy to commit trafficking in firearms. In addition to the 87-month prison term, Judge Howell ordered Smith to serve three years of supervised release. Federal prosecutors had requested a 108-month prison term. According to court papers, beginning in November 2023, ATF opened an investigation after a confidential source reported that Smith, then on supervised probation for a violent felony, was actively advertising firearms for sale by texting photographs of guns to prospective buyers, including individuals with prior felony convictions. During the next six months, Smith sold or arranged the sale of nine firearms to a buyer on six separate occasions. During the transactions, Smith sold his own personal carry firearm on multiple occasions when a supplier failed to deliver, then purchased a replacement for himself afterward. In early January 2024, as Smith and the buyer discussed an upcoming transaction, the buyer told Smith he needed the firearms because he was “at war” after his cousin had been killed. Smith proceeded with the sale. The buyer had also told Smith he was serving a criminal justice sentence at the time of the transactions. Smith acknowledged that he, too, was “on papers.” Smith arranged a total of six transactions from Nov. 30, 2023, through May 30, 2024, resulting in the sale of nine firearms. At least one of the firearms had its serial number obliterated. On Oct. 26, 2024, MPD officers conducted a traffic stop on the 1600 block of 16th Street SE and found Smith in the front passenger seat of a parked vehicle. Officers observed open containers of alcohol and discovered a satchel at his feet. Inside the satchel, in plain view, was a loaded Glock Model 19X 9mm handgun with a round in the chamber and 16 additional rounds in the magazine. The bag also contained a bank card and government-issued identification in Smith’s name. Smith has prior convictions for Simple Assault (2011), Attempted Robbery (2013), and Robbery and Possession of a Firearm during a Crime of Violence (2016), for which he was sentenced to five years in prison. He was serving a term of supervised probation from the 2016 conviction at the time of the firearms trafficking conspiracy. This investigation was conducted by the Bureau of Alcohol, Tobacco, Firearms and Explosives Washington Field Office, and the Metropolitan Police Department. The matter was prosecuted by Special Assistant U.S. Attorney Brendan M. Horan. Convicted Felon Sentenced to 87 Months in Trafficking
