How long of gun barrel count as a pistol?

In the U.S., under federal law, a pistol is defined as a firearm designed to be fired with one hand, and it typically has a barrel length of less than 16 inches. If the barrel is 16 inches or longer, it could be classified as a rifle, which comes with different regulations. However, some states might have their own rules, so it’s always a good idea to check your local laws too. For most pistols, though, you’re looking at barrel lengths well under that 16-inch mark, so you should be fine as long as you stick with standard options

So, for pistols, the federal rule is pretty straightforward: as long as the barrel is under 16 inches, it’s classified as a pistol. If it’s 16 inches or longer, it’s considered a rifle, and that’s a whole different ballgame. Most pistols you’ll find have barrels way shorter than that, so you’re probably good. Just keep in mind that some states might have their own rules, so it’s worth checking your local laws to be extra safe. Good luck with your first purchase—exciting stuff!
