Buy it immediately, then shoot it with tons of 38's, up to +P+. Limit the number of 357's, especially the 125 grain loads. You'll find out it is a 2&1/2" target revolver. It's quite well balanced and quick. It CAN be shot effectively at 100 yards, if your eyes are up to it, and your technique is good. If you want to carry it, don't use rubber grips, as they "grab" covering garments. They also contribute to inconsistency of grip, which open up groups. If it comes with factory "Magna" grips try a Tyler T-grip if you cant spring for a set of Herret's.
Yeah, 3" fixed sight 357's are better in some ways, but you can't adjust the sights for more than one load. I've a M19 2&1/2 that has become part of me. 33 years later she needs some tightening. Maybe take it to Terry Tussey next time I hit Carson City.
