I have a GSG 922 model. It is the GSG 1911, but with a 3.6in. bbl. and no bushing like the full size model. Mine has the full size grip frame. It is a fun gun, but certainly not built with the same quality of metal of a Colt 1911.......and thus, the reduced $$ on purchase. I have run a fair amount of 22LR ammo through mine, and it really likes the CCI MiniMag ammo. Enjoy you new "toy".
