q: I heard the z-grip was more comfortable- is it really?
a: well, for some folks it is. In this picture, i'm in the foreground. With my teeny-drop and 68 tank setup, my wrist is in a perfectly natural postion when I fire, and I like it that way. (I use a stock frame) No, a z-grip isnt more comfortable if you're like me and want your gun out in front of you.
However, if you're like my teammate in the background (shooting an intelli) and you put your tank on your shoulder or use a huge drop, a z- would probably be more comfortable. Notice how he has to contort his wrist.
