Yeah, we qualify quarterly and our guys average 800 to 1,000 rounds per year. Apparently that is “high cotton” for a Agency.
Guys in specialized units shoot more. The P229 I referenced with the broken slide spring box had upwards of 25k rounds without a single recoil spring change. Definitely operator error as all of our guns or supposed to have the recall springs changed out two years prior regardless of round count. For some reason my agency is stuck on the idea of a service pistol going 10,000 rounds with no preventive maintenance or spring changes. The only gun I have seen capable of doing that has been the HK USP compact series.

Most of the Glock issues I have seen have revolved around third generation 40 calibers or early Gen 4 9mms. The issues with both have been resolved in later generations.
