Glock
I simply don't believe that Glocks jam. I've owned several and shot the be-jesus out of them and I've never seen it. If it absolutely, positively must work, every time the trigger is pulled, no one comes close to Glock. In semi-autos pistols you buy, take from the box and shoot, no one is even remotely close. I've owned Sig, Beretta, Colt, S&W, Browning, Tangfolio, Springfield, and Glock (probably some I can't remember at the moment. I currently own Glock 23, Les Baer Premier II, Taurus PT1911, and a couple revolvers. Love to shoot the Baer and the PT1911 but if the chips were down and I had to have a self defense weapon. I'd pick up the Glock 23. Personally, I believe the Glock 23 is the the epitome of self defense pistols. Very few people have owned enough pistols, or shot enough, to truly recognize what a "perfect" pistol the Model 23 is for it's intended purpose. Even the plastic sights are worlds ahead of most combat sights for a fighting sight. The trigger hampers ultimate accuracy but you can hit a 6" circle at 25 yards off hand until your fingers bleed and the Glock will never stop. Just my opinion but it's based on owning many firearms and shooting them.
