I bought my glock in 1987. I've well over 30K rounds through it, and it has never jammed. Ever. Model 17, hardball ammo, usually winchester white box.
I have no other gun that I can say that about.
Having said that, I don't like them as much as I do 1911s. Weird. I loves my .45s., even though they're not as reliable.
Sort of like loving a beautiful woman that treats you like crap, and while you KNOW the homely girl next door would never, ever do you wrong, you still don't want to be seen in public with her...(sigh).
It's a pretty simple answer to this question, I think: If your life depended on the gun working, as in if you knew you'd be attacked by 30 people within 10 years, you'd start to actually love your Glock above all else; or if you were in war, and you depended upon your pistol to shoot every dang time, because if it jammed in the midst of battle, you'd be dead? You'd love the Glock above all else!
But since you're just shooting at the range, with your life not threatened, then it's all about 'having fun' and how the gun *feels* when you shoot it, and it how looks. But when the S hits the F, the Glock, even though not as good looking as the 1911 (I do love the 1911 looks, btw), it's still beautiful in its "ugliness;" because it's just so dependable! When you love something in spite of its "not so great looks" then you know it's true love! Not superficial lust, as in outward appearances only!
Okay, this sounds too much like loving a woman... I think I'm going too deep here when talking about guns.
In the end, Glocks are combat pistols; there's no beauty in death slaughtering, bloody war; it's all about survival. Glock was made for war, not for walking down the runway like some hot supermodel; not for merely 'having fun at the range' with, either.
But I think I made the point?
