I had a Model 625 in .45 ACP. It was wonderfully accurate with my handloads.
My objections were that it was stainless steel, which I'm not too fond of. Nothing wrong with stainless, just prefer blue steel, myself. Biggest objection was it had a round butt which necessitated making special stocks. My objections were its "just not my thing" type of issues.
As to its value on the used gun market, seems all revolvers with barrels longer than 2" ~ 3" aren't too popular. But then again...........
