My Glock 19X has upwards of 7000 rounds through it. I'm fairly certain that it would fire with twigs and leaves stuffed into the magazine, it's that reliable.

And that's with the cheapest, crappiest, and dirtiest steel and aluminum cased ammo that money can buy. And there was at least twice that I went over a thousand rounds without cleaning the thing. Predictably, it still went bang every time.

Factory parts are dirt-cheap, and you need them very, very seldom.

I know that they're as ugly as sin, but they work for me.
