Today I picked up my new Single-Six SS. This is my first experience with a Single-six. I was surprised to find that the hammer spring is MUCHO stout, i.e. it takes a good thumb to pull it back. It's much stronger than my 44 Super Blackhawk or my 357 Blackhawk. Heck, it's even much stronger than my BFR 45-70. Is this normal? Will it lighten up with use?
The answer to your question is: all Ruger SAs previous to the New Vaquero and 50th Ann. and 44 Lipsey's Flattop, use the same spring and length spring strut! So a Super Blackhawk. a Blackhawk, a Super SS and a Single Six have the same tension spring; 22 coils. Obviously the Super BH and BH with their taller hammers have greater leverage then the short SSix hammers.
The solutions are:
1. Clip 2 1/2 coils from the S Six spring. With a little dexterity and pointed nippers it can be done without even removing the spring. Unload the gun, remove grips and start at the hammer end of the spring cutting 1/2 coil at a time. Lay the gun on a padded surface, push one side of the nipper cutting tip down firmly along the flat side of the strut to get behind the first coil of the spring and clip. Wear safety glasses. Keep going beyond 2 1/2 coils if you like, but NOT more than 2 more full coils. If you cut the full 4 1/2 coils and have misfires, go to option 2 or 3 below. But 2 1/2 to 3 coils will make a noticeable difference and not cause misfires.
2. 2nd option: buy and install a spring kit; I like Wolf kits.
3. 3rd option: order a New Vaquero spring.
If you want to reduce the trigger pull by half (and I do this on all size SAs), just unhook one side of the trigger return spring under the grip panel. If it's too light a pull for you, you can just put it back. Or if you get a spring kit, use the reduced power trigger spring that comes in the kit.
You'll be much happier! Rugers are built 'hell-for-stout'! Any questions please don'y hesitate to ask or e-mail me.
