At about 18 months on the range as a rental at this point, the Glock 17, Gen 3, P-series SN has finally experienced its second breakage. The first one was at about 12 months. The trigger spring snapped. This pistol has the "dip" extractor, a 336 ejector, and the MIM locking block. We estimate that this pistol has seen at least 20.000 rounds, although 25.000+ is likely more accurate. (If every person who has rented it only shot one box of ammunition, it would have seen just shy of 19.000 rounds. We keep track of number of times rented, not round count.)
Today, a customer alerted me that the pistol was not functioning properly. He said the slide was locking back at random. I asked him to shoot the pistol while I observed, which he did. After a few rounds, the pistol locked open just as he said it had. An inspection quickly revealed that the slide stop was malfunctioning, just flopping about loosely. Removal of the slide stop confirmed that the source of the problem was a broken slide stop spring.
While a new part was being brought up from the gunsmithing department the pistol was lubricated. The part was replaced, and back onto the line it went. She's still humming along.
Interestingly enough, the Glock 19 (Gen 3, dip extractor, 336 ejector, old non-MIM locking block, P-series) also experience an issue at the same time. The customer claimed the pistol would not fire. I cleared it, and attempted to dry fire it. It would dry fire, but it had about a 20# trigger pull. I field stripped the pistol, observed no excessive fouling or foreign material, nor did I notice any damage to any parts. I lubricated the pistol, reassembled it, and the issue seemed to be resolved. The cause of the incredibly stiff trigger is still unknown.
Just thought someone might be interested in the issues we observe on these high round count pistols.
