I have owned and shot J frames since 1967. My favorite is the Bodyguard. I own three M38, two M49, five M649, one M649 J Magnum w/ MIM parts and three M638. I have shot them all and the best shooters are the M638, the M649 are a close second. I smoothed the internal parts and lightly oiled the friction points. I did, however, take the locks out and replace them with "The Plug". I resisted the new Smiths until I bought my M638. They seem to me to be smoother, more controlable, more comfortable, as accurate as any J frame I have shot. I use mine for BUG/OD/CCW. My wife carries a M638 as well. FWIW
