Reducing Hammer Pull Weight on Uberti

[The Dutchman]

Hi guys I want to reduce the weight of the hammer on my uberti cattleman and although there are several discussions that go over this already my question is how can you do this while still maintaining reliability to ignite the primers? Would a new longer or thinner firing pin work? Or would I have to use cartridges with sensitive primers? Thank you

The SAA design has a lot of reserve power. Most of the limber spring kits will retain enough hammer fall to fire decent ammunition. I know there are some out there so light as to demand Federal primers but by the time you get that far the lock time is getting pretty slow.

Thank you for the response. Ok that's good I'll get a reduced power spring from Wolff then. Would you recommend still using federal primers to be on the safe side since I reload my ammo? Or does using the primers offer some disadvantages?

I used a lot of Winchester primers in my single actions, the Colt with an Eddie Janis action job, the Cimarron with a DIY.

I have an original time period Cattleman and had to change and fix a few springs. The Wolff reduced power spring gave me the first misfire in 30 yrs+ of owning it. I put the old one back.

Any SA without debris in the lock-work will fire any standard primer with a Wolff or Wisner spring kit installed.

The only risk is less accuracy if you go too light as the lock time increases each pound you go down.

There is a 'sweet spot' between to heavy stock spring, and too light extra reduced power springs however.

Too heavy jars the gun off target before the bullet clears the barrel.

Too light gives you more time to move the gun after you squeeze the trigger, but before it fires.


You just need to experiment with what spring weight works best for you.

It's always a good idea to reduce the roughness in the action when swapping springs. Eliminating friction pretty much negates any perceived locktime issues with light springs.
