Michael Bane offers his.
Some legal type guy does too.
Let’s get the obvious out of the way, it’s stupid. Saying that using it in a way other than intended “redesigns” is asinine. If I use the magazine well as a forward grip, I’m not redesigning it. Also, US Code defines a handgun:
(29) The term “handgun” means—
(A) a firearm which has a short stock and is designed to be held and fired by the use of a single hand;
I guess if you’re using two hands to shoot (like you fucking should), you’ve just redesigned your Glock.
My guess is what really happened is the first letter was approved without appropriate supervision; or they didn’t realize the can of worms they were opening.
As for what to do, I’m keeping mine as a collectors item. I imagine there probably won’t be many more made.
As for what to do legally, I dunno. Perhaps a class action suit against ATF for relying on their initial letter?
