Hi Brian,
I am not the one to give advice on 45 colt but I have some experience with a Ruger SBH Hunter with a 2x scope and a Redhawk 7 1/2" with the same 2x scope. Both handguns are in 44 mag. Do you by any chance own Marshall's book? It gives lots of details on proper bullet size, fire lapping and all that. Those are real biggies in making the bullets go to the same place on the target. You can also search this (and the previous) forum for lots of details.
You asked what is possible with a factory standard gun. I will assume proper bullet fit and firelapping. I am not a handgun target shooter and just do not like scopes in the field, but I was able to get good accuracy. My best groups with the Redhawk & 2x scope ran about 3" at 100 yard from a benchrest. With the SBH Hunter I was never able to get my best load under 4 1/2" @ 100 yard until, out of desperation, I cleaned the barrel until it squeeked and shined. Suddendly the groups fell to 2" @ 100 yards. I never noticed such a difference with the Redhawk. Personally I believe both guns were shooting better than that but I simply could not shoot any better. By the way, this was also the result of a lot of practice and learning to become super calm before shooting.
I'm sure others can give you more specific info specifically to 45 colt, but these were my experiences. Hope it is of some help.
God bless................. Bill M
