I have had an LCP since early fall of last year. My experience is the same as stated in the American Rifleman article.
I have found it is very particular as to the brand of ammo. Before one starts carrying this weapon on a regular basis be sure you know the ammo is compatible. Or else you might find yourself in a compromising situation with a FTF or FTE.
This is IMHO not a range weapon. It is not for me a very comfortable weapon to fire. About 50 rounds of firing and I am ready to put it down.
As also stated above, I find it is only reasonably accurate up to 12 to 15 feet. Sights are too small so it becomes more of a point and shoot weapon. I pretty much practice shooting one handed without sighting.
For those times when I need deep concealment, the LCP works for me. However, this is not my everyday carry weapon. I usually carry a sig P232 or P229 depending on the situation. I have pants with deeper pockets and find that the P232 with a Mika pocket holster works just great for me.
