Out of curiosity, I asked a sales clerk at the range which guns in the rental required the most service and which the least.
He said the worst offender was the Glock.
The spring in the trigger breaks. Glock fixes them promptly, and these are very abused public rental guns, but still! You pull the trigger to fire a round, apparently and it won't thereafter reset forward, is my understanding. Though I could have gotten in wrong, now that I think about it. I guess the spring in that little tongue safety thing would cause a problem? I'll try to get clarification next time. The facts are definitely: "Most breakage? Glock. Trigger spring. Fails. No workee." though.
No one had ever asked that question before, about which range gun does the best and worst. He couldn't think of number 2 or the most problem free semi they had because he hadn't given much thought to the guns that DIDN'T aggravate him.
The revolvers give them the least problem, and the issue they have is one Saucy Trollop has had with her. The screw that holds the yoke that the cylinder is mounted on backs out a little bit, then the whole yoke assembly falls out on a reload. They can fix that in the store if the screw hasn't actually left the gun completely, nary to be found without a good range sweep down.
Note: This is one clarque at one rental counter. Not a big statistical sample. And maybe he's a Glock Hater. Still, intriguing.
