I know that this thread is almost 3 years old, but there seems to have been some "new" developments. I recently became interested in a .45 Colt / .45 ACP combo Redhawk due to: alot of .45 Auto ammo laying around, plus the desire to get a .45 Colt handgun to hunt with "heavy" hunting loads.
It seems that Wild West Guns up in Alaska makes a "Wolverine" revolver based on a Super RH that is converted to shoot .454 Casull, .45 Colt, and .45 ACP using full-moon clips. They credit "TK Custom" for the clip conversion part.
This same TK Custom company is in Illinois, and offers .45 Colt / .45 ACP full-moon conversions on Redhawks, Super RH's, S&W 625's, and Colt Annaconda's, plus alot of other guns & calibers.
It appears that once converted, these guns will REQUIRE the use of full-moon clips for ALL loading, even with the rimmed cartidges ???
Anybody else learned something NEW about .45 combo stuff this since 2001 ?
Thanx, Dave.
