Get a 625MG in .45 Colt - made again last year as depicted on pg 29 of S&W's '06 catalog - check your dealer for current availability. I've had a 7.5" SRH .454/.45 and a 5.5" RH .45 - both bought new. The 625MG groups better with standard 'cowboy' type loads - and is a great 'plinker'. Based on the 21,000 PSI .45 ACP, the 625 is suited for a bit more oomph than the standard .45 Colt SAAMI fare, although not up to the Redhawk's level.
My SRH didn't group well at low speeds - the RH grouped better. The MG's actually do better at 25 & 50yd with standard loads - and were just too much fun. Of course, they are 9-14 oz lighter, too. I kept my MG pair - depicted below - as they were more reliable and had far better triggers than that RH. Oddly, they have more metal between chambers - .062" vs the RH's .059". The RH's ejector star can skip over the .45 Colt's dimunitive rim, too, making 'fast' reloads impossible. All three use the HKS #25-5 speedloader. I have no ftf's with my MG's - the RH would still occasionally ftf with slow trigger pulls, it's trigger truely being an 'acquired' taste (The SRH has a better trigger!).
The .454 SRH in 7.5" (No more 9.5" !) is great for 'ultimate' .45-ish power - and a scope. I've gotten 1.5" 5-shot (allow a flyer) groups at 50yd from sandbags/scoped with Hornady 240gr XTP .454 Casulls (1,985 fps - 2,100+ ft-lb) - and 6+" for mild .45 Colts! So, for a .45 Colt plinker - with either the Speer 250gr GDHP or 255gr LSWC (see picture) at 840+ fps - or a wimpy 250gr LRNFP at 700 fps in a .45 Schofield, aka 'short' Colt, case, get the Mountain Gun. Just don't mind the smoke trail on the shot .45 Colt cases - all of these guys still use the 'oversize', or black powder, .45 Colt chamber ID. I think only Freedom Arms makes 'tight' chambers. Still, the .45 Colt in a MG is fun - and decent woods protection.
