Revolvers were the handgun of choice for most of the 20th century, not only for law enforcement (for which I count myself among those worthies), but for almost everyone else. Sure, a few folks had 1911's or BHP's, but most of us were just happy as clams with our Colts and Smiths, and it really wasn't until Glock introduced the G17 that everyone jumped on the bottom loader bandwagon.
You said you wanted to "buy another semi-auto" which implies, at least to me, that you probably already have a semi-auto. If so, why do you feel you need another?
I carry a Model 36 more than any of my other hand guns and don't feel unprotected, which seems to me to be the whole point of CCW.
