If there’s one golden rule for firearms laws, it’s this: you can’t put a stock on your GLOCK (or any other pistol, for that matter) in the US of A without an NFA tax stamp. There are a couple manufacturers who make such GLOCK stocks, but they all require a tax stamp first or a friendly local ATF agent might come a-knocking at your door. That rule has been stretched to the breaking point recently by such innovations as the pistol arm brace, but the folks at Accurate Pistol Systems have taken it upon themselves to try and stretch it a little bit further with their 1SHOT system . . .
How is this legal? There’s a catch … the product doesn’t attach to your firearm.
It looks like the only thing keeping the stock and your pistol together is friction and the force of your hand on the grip. That’s a brilliant way to get around the NFA regulations: since the item is not actually affixed to your plastic fantastic, the gun hasn’t been “redesigned” and therefore is not subject to NFA regulations. For now. I’m taking bets on exactly how long it takes for the ATF to write another letter using flawed logic and making this illegal somehow.
