Isn't anyone going to mention the Ruger SP 101?
I really like the SP101. Mine is stock except for a set of Hoque grips. It must be pretty tight as I get a chronographed 1,300 fps with 13.5 gr of H2400 and 158gr Lead SWCs.
I thought about getting a Smith Perf Center M66 3", but I didn't like the muzzle brake, plus I've had a run of bad luck lately -- everything I buy seems to have some sort of problem (not limited to guns). Thought I let Murphy rest for a while. There's no real good reason to spend the money on the M66, I'm sure the Ruger works just as well -- although the M66 I handled sure was sweat.
