Trijicon HD's.
Mine has been flawless with Hornady Critical Defense, Federal Low-Recoil Hydra-Shok, and UMC ball. Only ammo it didn't like is that Tula steel cased chitt from Wal-Mart.
Mine is stamped with the "1" revision frame/internals, but shipped with very first series magazines. I bought two more "02" stamped mags from Midway and haven't had any issues with either and haven't had any FTF/FTE (other than Tula) or any of the slide lock-back issues with rounds still in the mag.
I don't doubt there has been some problematic G42's, but I think a lot of it is people inadvertently hitting the slide release, limp wristing, cheap ammo, and a whole lot of re-reporting of troubled guns all across the 'net.
"My cousin's uncle's co-worker talked to his brother-in-law who is a cop and he said he was at the range and someone had a rental G42 and it malfunctioned".
