My G42 got squirely at a carry gun match. Ran with FMJ and then decided to run a mag of HPs and it seemed to fire semi out of battery, jammed. It's done this before. I intend to test with at the square range with HPs and will report in semi sub forum later. Weird flash from the ejection port, jammed - racked it, clearly and it shot the rest of the HPs - they were Barnes TAC-XPD 380 ACP Ammo 80 Grain.
It had correctly chambered and shot about 36 Blazer FMJ before, so I think my racking skills and mags were OK. It shot the rest of the stage with FMJs ok. The gun was lubed before the match.
About shooting the G42, out of 54 targets, 44 As, 8 Cs, 1 D and 1 M. The last two were too low, I think I was used to my big gun trigger and gave the little guy, a too enthusiast pull. Seventh in terms of As. Most guns were the more compact 320s, 365, etc. No other 380s. The guy who collects the empties gave me some jocular shit about 380s. My times - forget it as I stroll from position to position.
So I'm ok with my close in shooting skills with the gun BUT - I don't know if I trust it with a load of HPs or carrying it with just FMJ. Thus, it's going back in its coffin till I can test it as the square range with more HPs. The 432 will become my pocket gun of choice.
When I first got the 42, it was a horror, jamming on everything, firing partially out of battery. Went back to Glock and now ....
