I have one of the Glock 17 models. It's a fun little gun and shoots pretty well. More kick than I would have expected from a 9mm carbine. Not bad, just more than I expected.
I have one of them in .40 (glock mags), like everyone mentions, its got some kick. short length of pull and some people have a hard time lookin down the sights. That being said, very portable, fun to shoot, accurate, and reliable.
I bought mine on gunbroker what is cool is it uses Glock 9mm mags so you can get 33rd mags for it. I have not gotten to shoot it yet but am looking forward to it. It folds up nice for a bug out bag.
