Shoot one of these and you will never go back.
Glocks are alright for their intended purpose. But when considering a purchase of something that is meant to have hot lead coming out of it at 1100FPS I tend not to go for "cheap".
I've also never had a jam out of my either of my P7s. They are also considered one of the safest guns available. You have to be holding it properly for it to fire. Let go and it's safe again.
