I remember reading a article by Ross Seyfried that said stronger than factory hammer springs really help the Ruger single action. Faster lock time and harder primer hits. In my stainless Bisley I installed 26LB power main spring. I know the one thing it did was really make the trigger pull a lot heavier. Do you really need these heavier hammer springs? Do they really help a Ruger single? I am thinking about putting the factory back in to get the good trigger pull I had. I installed a wolf trigger spring in the gun. Any advice would be appreciated.

Well, we all have our ways...........

I will "tune" up the Lockwork in my shooters. I'll "slick up the action". I'll reduce the trigger's "creep". I'll also make sure the mainspring is in good shape and will often swap out the original for a slightly stronger spring. Inspect the firing pin and its' related action parts.

The overall result shouldn't make the trigger pull much "harder".

+1 to Flatgate.
It's all about getting the parts to work together smoothly.

Look at the post by "was1911" and what he does to modify a gun.
Read the part about "round holes & lapped pins" carefully. That is the type of stuff that makes a guns action slick, smooth, and easy to operate.
Before ANY springs get swapped around, a smoothed up action is the basic thing anyone should do.

I regularly shoot a .45 SS Bisley convertible, I can't imagine a heavier firing pin strike. The primers on my cases are hit so hard and deep, with the factory spring, I'm wondering if I'm not deepening the primer pocket. Additionally, I don't worry too much about lock time on a single action revolver, I consider it beneficial to developing good follow through habits.

Good luck,
Steve

I think the fuss about heavy mainsprings is all about lock time. Yup, single actions have a heavy hammer and lock times are longer than a semi-auto. Lock time alone is not a big deal. Reducing lock time, in my opinion, won't make you a more accurate shooter. The primary function of the mainspring is to provide enough energy to reliably ignite your primers.

Now there is an interesting idea for a single-action. A reduced weight and skeletonized hammer. hmmmmm

That would 'shore look funny. :roll: :roll:

I asked/proposed the same idea over on the singleactions board a couple of years ago. Overall the more seasoned users suggested that the end was not worth the means.
