Just an update - I've already put this info on its own thread here earlier this week, but thought that it might be good to include it on this thread.
I tried some Buffalo Bore 95-grain FMJ flat-point .380 "+P" through the LCP. I now have an extra-power recoil spring on order from Wolff and so I thought I'd give it a try in the little locked-breech gun. (Note that there is no such thing as SAAMI-spec ".380 +P" - these rounds are just overpressure, pure and simple, and Ruger would advise against their use.)
They shot fine. I only shot five. Here are the velocities in FPS (5950'>sea level, 41°F, c. 15% humidity):
1066
1075
1112
1074
1133
M 1092
ES 66.98
SD 29.01
That's really cooking with gas - for any .380, but particularly out of a sub-3" tube. The rounds were decently accurate at ten yards - they'd all group into a heart at that range - but they were not the most accurate round from this gun. I think that the one to the upper left is my fault - they were really snappy and pretty darned unpleasant to shoot.
(Knife point is at point of aim)
It was really snappy and kicked noticeably hard. Primers looked fine (like that means anything) and gun functioned fine. Brass was thrown back about 20 feet. I stripped the gun afterward and examined every stress point I could think of under bright NM sunlight through a magnifying visor. I could find nothing at all out of the ordinary.
Apologies for my crappy cell-phone pictures - I didn't think to bring the camera.
