I have an LCP with the viridian laser as my every day carry, and I love it
It's a good gun and Ruger stands behind their products. From what I read the LCP feeds well with pretty much any ammo which can't be said of most small .380's. I ended up getting the Kahr cw380 just the other day but haven't fired it yet. One ammo choice I wanted was the Leheigh Defense with extreme penetrator bullet but they don't recommend it for the Kahr p380 or cw380 because of the steepness and slight offset alignment of the feed ramp on those guns.
On the video on the Leheigh Defense web site the p380 fed just fine but they said it did have a couple of feed issues that weren't on camera. I read somewhere else that someone sanded the sharp corners of the bullets just a tad and they fed 100%. That might decrease the wounding ability of the bullet though, not sure. They didn't test the LCP but I'm betting it would feed fine. I'm probably going to get some and see how it goes in my cw380 because the tests I've seen on this bullet are impressive.
