I just picked up one of these the GSG 1911 .22LR.
Here is a picture of mine. Sorry if it is a little fuzzy.
I have only shot a few rounds through it and it looks like it has great potential. I am planning on giving it a work out tomorrow, if the weather works with me. The gun feels just like other 1911s that I have fired before. The controls are standard and familiar. The Grip safety is functional, just like a .45ACP 1911. I think for someone that wants a dedicated .22lr 1911 this is a great choice. The magazine capacity is 10+1. I'll put more info in this thread after I give the pistol a workout.
