I would like to second what Jim Keenan, Nick1911, WT, thowell, scubie02, grimjaw, SharpsShooter, and Sistema1927 said.
I have determined that .38 caliber revolvers are what feels right for me. My S&W 642 is the perfect fit for how, when, & where I carry. And I think it is almost impossible to dispute the tactical positives (.38spl +P/lightweight/hammerless) of this snub nose.
Just my thoughts.
