Got a new LCP 380 and today was 1st range session. I cleaned it prior to going.
Ran a couple mags of FMJ, no problem.
Shot FMJ one hand weak hand no problem.
Shot the Fiocchi XTP and had fail to feed and had bullets get stuck in mag.
Didn't think to take pic but HP bullets would get stuck feeding into chamber.
Same fail to feed issue with Sig V-Crown.
Went back to FMJ again and no problem, not even one hand weak hand.
I'd had enough of shooting the LCP at that point.
Did some measurement when I got home.
V-Crown - .946
FMJ - .975
Fiocchi - .985 (these would stick in mag)
The Fiocchi fail to feed is most disappointing, as I had intended that to be carry ammo.
For now I'd only be comfortable carrying the LCP with FMJ.
I wouldn't mind trying Underwood extreme defenders with the Lehigh bullet but they are not cheap and I'm a little gun shy given that the V-Crown also had feeding trouble.
The LCP shot POA at about 5 yards, brass ejected fine and not once toward my head.
