I have two 3 inch S&W 36 revolvers and a three inch S&W 60.
I carried one as my primary off-duty gun for 35 years.
I really like the way the 3 inch balances. All my guns have Pachmayr rubber grips. I've always carried them in OWB leather holsters.
I know a lot of people prefer a shorter barrel on a small revolver to allow pocket carry, but I've always preferred to use a holster.
I have a 3 inch heavy barrel S&W 650 in .22LR that I use as a practice gun.
