Now this is interesting. Ruger is getting into the .45 ACP revolver game. They have just announced a new version of the Ruger Redhawk that will handle both the .45 ACP with moon clips and the .45 Colt.
The specs are below:
Material: Stainless Steel Finish: Satin Stainless Front Sight: Ramp Rear Sight: Adjustable Barrel Length: 4.2" Overall Length: 9.50" Weight: 44.00 oz. Grips: Lasered Hardwood Twist: 1:16" RH Grooves: 6 MA Approved & Certified: No CA Approved: No Capacity: 6 Suggested Retail: $1029.00
It's a bit pricey but they are still making double action revolvers unlike the bankrupt Colt. I have a couple Ruger revolvers and they are solid, well-made handguns.
UPDATE: Ed Head has part one of his review of the Ruger Redhawk in .45 ACP/.45 Colt up. Ed is one of the people that Ruger sends firearms to so that they can be wrung out before launch.
