I too have jamming with my lcp. I think it is with jhp ammo. It has only recently happened trying to manually cycle rounds through gun. really love this little gun. If I have to I will carry it with only fmj. where I carry it is secluded with not much concern with over penetration. The shell gets jammed right on top of gun with half in and half out of ejection port. gun was sent to company. came back with new barrel and mag. Worked flawlwssly at range . Same ammo now jambs when manually cycling. perhaps gun will fire rounds that wont cycle manually. Advice welcome.
