The Kahr is a nicer gun in that it has all the features of a full sized weapon unlike the LCP. That being said, in my situation I wouldn't trust the P380 with my life and I would the LCP at this point. My P380 went back to Kahr a few days after I got it and the slide was replaced. In my opinion the P380 is a hit or miss in terms of reliability. Its a newer design compared to the LCP, so I'm sure that's part of the problem. If I already had a reliable LCP with CT laser grips and the recoil of the gun nor the trigger pull bothered me, I'd stick with that.
Kahr-better trigger, real sights, +p capability, stainless steel, slide lock, polygonal rifling, 2 magazines, softer recoil
LCP-goes bang every time
