If you don't plan to carry it as a CC gun, S&W's superb Model of 1955 Target would be a good choice...and assuming that you don't screw up the bluing, it'll be worth as much as you paid for it down the road. Mine is a pristine model, bought from a local dealer back in '88 for the paltry sum on $325...came new in the box, presentation case with all the tools too.
As a shooter, it's right up there at the top of the list...prefers 200 gr LSWC's of the H&G #68 style and cast from more or less pure ww's. 1" at 25 yds is the standard they set, and it'll do that with some of Sierra's 230 fmj's. It's trigger is old school S&W light and I've garnered a few 'possibles' at 50 yds with it, in my NRA Bullseye days.
Expensive? Hell yes, but worth it if you treasure a truly beautiful target gun, there are none better.
YMMV, but it'll do for me. Rod
