A friend of mine is buying one of these and he brought his Dad's into work for me to check out. I think i like that thing. It's chambered in either 9mm or .40 s&w and the mags from your Glock Or Beretta handgun will fit it. I am hoping they will make a set up that i can use my xdm 9mm mags in as i have a s load of them. Anybody have one of these that can comment? I havent shot one yet but I like the fact that it folds to 16" and can be stuffed in your BOB. Beats carrying around a rifle.
