High Spade Mikey Wilson Posted July 9, 2022 Share Posted July 9, 2022 Anyone know what pound spring the stock hammer spring is in the Uberti Cattleman pistols? Link to comment Share on other sites More sharing options...
Roger Rapid Posted July 9, 2022 Share Posted July 9, 2022 My guess is around 40-45 ounces. I can measure one if you need to know. RR Link to comment Share on other sites More sharing options...
High Spade Mikey Wilson Posted July 9, 2022 Author Share Posted July 9, 2022 No need Roger. Thanks! I saw a video on changing out the hammer spring and replacing the bolt spring, which I just had to do. They talk about changing the hammer spring to a lighter spring, but never say what the stock spring weight is to start with. Link to comment Share on other sites More sharing options...
Abilene, SASS # 27489 Posted July 10, 2022 Share Posted July 10, 2022 I've seen some stock hammer springs that were much lighter than others in both new Uberti and Pietta. So I guess it is a YMMV thing. Link to comment Share on other sites More sharing options...
Roger Rapid Posted July 10, 2022 Share Posted July 10, 2022 High Spade ... My curiosity got the better of me and I wanted to see if my memory was correct. Here's a photo of three springs for the Uberti (and other) SAAs. The one on the left is the typical spring found in original Colt SAAs and in most Uberti SAAs. It delivers a hammer spring tension of 32 ounces (not 40-45 ounces as I previously stated). The two aftermarket springs on the right provide lighter tensions; the middle one provides 22 ounces and the slotted one is 24 ounces. Of course, adjustments can be made to each of these springs to lighten their tension. I use a modified spring like the center one and have them set to 20 ounces. You can go lighter but you fall into the risk of light firing pin strikes. (I know a few SAA shooters who have hammers set to 16-18 ounces.) And, much has to do with the type of primers you are using. RR Link to comment Share on other sites More sharing options...

I'd like to reduce the hammer spring tension, but I don't want to put springs in that will require me to use soft primers. You told me what I needed to know. Thank you kindly!!

Roger Rapid Posted July 11, 2022 Share Posted July 11, 2022 Hi Spade... Both of those aftermarket springs, or any springs that deliver a hammer pull of 20-22 ounces will detonate CCI primers. The springs are available from several sources, but I know that VTI Gunparts in Connecticut carries them. RR Link to comment Share on other sites More sharing options...
Abilene, SASS # 27489 Posted July 11, 2022 Share Posted July 11, 2022 Current CCI primers are softer than those of old. Maybe not Federal soft but pretty easy to set off. I've been using CCI small rifle primers for the last couple months with lighter springs and no problems. (YMMV of course) Link to comment Share on other sites More sharing options...

Imis Twohofon,SASS # 46646 Posted July 11, 2022 Share Posted July 11, 2022 A thin leather washer between the frame and the end of the spring will lighten the existing spring and allow some adjustment. Punch the screw hole out and you have it. Imis Link to comment Share on other sites More sharing options...
High Spade Mikey Wilson Posted July 12, 2022 Author Share Posted July 12, 2022 Thanks all. I have a pair of reduced hammer springs coming from Taylor's. Link to comment Share on other sites More sharing options...
