Always interesting the guys that truly think Glock pistols won't choke. Glock is as reliable as any other modern good quality semi auto. No more, no less.
I've got nine that have never jammed. One came from the factory with a defective part. They replaced the part and sent it back, and it's been perfect since. That was a Model 21 (.45 ACP).
The overwhelming majority are super reliable from the factory, and if there's a problem, it's obvious immediately. I suspect that 21 had a defective part because the gun shop guys used it to practice detail stripping Glocks, and damaged a small part in the process. That's my suspicion, because they all talked like they like to do that when they were bored.
You can shoot a Glock dirty and it will keep working, although relubing it every five hundred rounds is a good idea, even if you choose not to clean it but once in a thousand rounds.
