I did an action job on a friends Ruger Super Redhawk in 480 Ruger caliber last night. It really slicked up well. I used a Wolfe Spring kit which comes with two trigger return springs (12# and 10#) and three hammer return springs (12#, 10# and 9#). The trigger took the 12# spring and returned with a snap, the hammer had more than enough zip with the 10# spring. A little polishing and some Brownells super lube in the right spots and it became gave a very slick D/A and S/A trigger pull. I loaded six rounds and stepped out back to test fire it. Three rounds D/A and three S/A gave perfect results with some Speer 325 grain JSP's and a case full of H110 sparked with CCI-350 primers in what was original Hornady factory ammo brass.
Working on this gun is a real pleasure. They are very well designed from the perspective of assembly and disassembly. Very simple, strong and rugged. The trigger assembly contains all the lock work guts except for the hammer, strut and spring of course and is easy to get out and in with minimal effort and expertise. The gun shot into one ragged hole at 25 feet so I think accuracy is good, granted a very short range for most handguns. From start to finish including loading six rounds of ammo and shooting took only an hour. The D/A trigger pull went from 17# to about 9# and was very smooth. The S/A pull ended at about 3.5# with no creep. This action will impress even the S&W fan, it was that smooth and crisp. What a work horse this gun is, a little bulky (this model has a 7.5" barrel) and heavy but not for the caliber. Weight in the right places and with good grips is easy to control. For those of you who have one of these in this excellent caliber you have a serious duty hunting handgun.
