Ruger has two which make the cut: LCP & LCR.
Picking just one is a tough decision.
I'll have to go with the LCR inasmuch as I bought one which pretty well sums up my thinking (but if I did get an auto it would be the LCP).
Both are great for CC. I don't disqualify all others, the manufacturers seem to be recognizing the true needs of the market and this makes for a great selection, but tough choices. Which is exactly what it should be.
