Hi all,
Thanks for the help I know this topic has been discussed before but It doesn't seem like there is a definitive answer. I've been having intermittent jams with my usp 45 expert, and occasionally with my usp 45 standard. I think it's what's called a three point jam (please correct me if im wrong). Round appears to not slide under the extractor properly and requires a palm bump on the back of the slide to send it into battery. Seems to jam on first slide rack mostly, but slide seems sluggish intermittently like its struggles to strip a round from the magazine during firing, there is a cartridge rim wear mark on the extractor face like its snapping over the rim of the round during feeding. Any ideas as to what may cause this? Im trying to not spend a bunch of money chasing parts fixes. I understand extractor or possibly mag spring issues could cause this. Any insight is greatly appreciated! BTW, these jams mostly occurred with hornady HAP reloads at 1.235 coal, however they also occurred with fmj reloads and factory armscor fmj rn ammo 1.25-1.265 coal.
