Thanks Bill and Mike.
I broke both guns down to look at the profile on the firing pin stop and there is a difference in radius. The Ruger has a "flat" before it "blends" to the slide. The Colt doesn't have this flat possibly giving the Colt a larger radius. I would not attempt to change that and will try some lighter springs as Mike suggested.
Just as an aside, what kind of loads would they be shooting with those extremely light recoil springs. I see Wolf goes as low as 5 lb. Don't get me wrong if I can get the Ruger functioning similar to the Gold Cup I will be happy shooting the loads I use in the Colt.
While I had both pistols apart I tried the Gold Cup recoil spring in the Ruger to see what difference it would make. I can easily cycle the slide on the Ruger with that Gold Cup spring installed even with out cocking the hammer first. That was just a quick try and both guns are back to their normal configuration.
Mike I think I will order one of those kits from Wolf. They have one with recoil springs from 15 down to 11 lbs. While I am at it I will also get their hammer spring kit which has 19, 20 & 21 lb. springs.
Again thanks for the help.
