I got the factory stock extension with the gun as well as an approved Bullet Button. The gun as it comes from the factory is not legal in CA due to it's length of 29.5' (needs to be at least 30') Fits in a 3 day backpack easily and is the perfect compliment to my Glock 35 as it uses the same mags and ammo but gives me an honest 100 yard range. It folds in half and is about 18' long when folded. I got this gun because it is very compact and offers a lot of firepower.
Right before the end of last year I acquired a Kel -Tec Sub 2000 in.
