I had a buddy on the police force let me go shoot his Glock .40, and while the gun itself was extremely nice I'll throw out a couple things to think about. They may not be any big deal to you, but in researching the issue on the 'net, I've seen others complain about the issue as well.

Every casing ejected right back into my face, or at least towards it. About every third piece of brass would actually hit me somewhere on my head.

The other thing was that the sights aren't adjustable -- at least not without replacing the whole rear ramp. I qualified expert with every weapon I trained with in MP school, and did a LOT of hunting growing up. I want my bullets to hit where I aim -- PERIOD. At approximately 15 yards, the POI was off by about four inches; granted, it would "work", but if I want to shoot someone's eyeball out, dangit-- I want to hit their pupil.

I've since expanded my search in handguns with adjustable sights on the pistol so that I can fine-tune the POI.
