I use my LCP as my primary carry probably 60% of the time (the rest being my LCR .357 or HK SK 9mm). I shoot all of my pistols on a regular basis with emphasis on my carry pieces.
Yes, the LCR isn't a very pleasant gun to shoot but not many pocket guns are. I usually go through 5-8 mags when I take the LCR to the range. I find it easier to shoot the smaller guns after I've shot my larger pistols, the harsh recoil not seeming as bad after going through 100-150 rounds of .45ACP and/or .357 before moving to the little guys. I think my hand has gotten used to the LCR because it doesn't seem as bad now as it did for the first few hundred rounds.
