I've got a 1989 625 like that but with the 3" barrel and no target trigger. I've shot two of those 5" models and they are a pleasure to shoot. According to the Ammerican Handgunner Nov 89 review, the chamber throats are held to 0.453" which is supposed to improve cast bullet accuracy. The full moon clips and all the toys are fun too. A good gun for reloaders, no chasing brass. One small annoyance is the chambers aren't chamfered. I paid about $440 for mine in a store back in 90. I think retail list was $535.
