Good info so far, I’m compiling data for customers who often ask where I work what holds up the best for classes where pistols can be run hard. So far it sounds like 9mm Glocks are pretty universally recognized as being solid. Sounds like some older Sigs too, as well as H&Ks. I mostly shoot HK and Glock but often wonder about the 92 series as well.
Some customers have variations on the question, such as if they’re looking for a specific caliber handgun that holds up well. 9mm, .40 S&W, .45 Auto, and rarely, .357 SIG.
I’m in an area where certain service members are basically given blank checks to procure what they want locally.
