Nickel City Dude Posted November 30, 2020 Share Posted November 30, 2020 Here is the story. I had to take my two Uberti 1873 Gunfighters apart to have some work done on them. They have the safety hammers that I never had any trouble with before. I never had to remove the rod that sits inside the hammer to push the firing pin out when I disassembled them or reassembled them. Is there a special way the rod should be orientated? I am using Federal large pistol primers in my 44-40 cases. Some fired fine and others did not. Any incite to my problem would be appreciated.

No, I was very careful not to mix the parts up. The same parts that came out of the gun were the same parts that went back into the gun. Link to comment Share on other sites More sharing options...
Warden Callaway Posted November 30, 2020 Share Posted November 30, 2020 I only did this one time (so far), I forgot to tension the hammer spring. But surely you wouldn't have forgotten on both guns. Link to comment Share on other sites More sharing options...
Cliff Hanger #3720LR Posted November 30, 2020 Share Posted November 30, 2020 As a commercial loader for many years for cas, I would check the seating depth of the primers. If they are not set all the way to the bottom of the pocket or if there is dirt in the cup keeping the primer from getting to the bottom of the pocket, it can take 2 hits from the firing pin to set the prime off. It is not always the obvious parts that are the problem. Maybe the gun reassembly. May be the primer setting. It might even be the shooter has start drag their thumb against the hammer as it falls. Chase the issues, one at a time. Not all at once. Check and eliminate 1 possible problem at a time. Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted November 30, 2020 Share Posted November 30, 2020 Knowing the history of that FP safety. I'll Bet it's the gun. See about locking the FP in place. OLG Link to comment Share on other sites More sharing options...
Sedalia Dave Posted November 30, 2020 Share Posted November 30, 2020 Check that the grip frames are on straight and that the hammer is not dragging on a bur. What work was done to them? If you fire slowly and deliberately making sure the trigger is held fully rearward does it happen? Link to comment Share on other sites More sharing options...

Turn the mounting screw all the way tight. I've at times just snapped the spring under the hammer and forgot to tighten the screw down. It makes for a wonderfully light hammer pull but not enough power to bust a cap. Link to comment Share on other sites More sharing options...

Nickel City Dude Posted December 1, 2020 Author Share Posted December 1, 2020 I think I had a bad batch or primers. I took them out today with cartridges I made for a new box of primers and they all worked fine in both guns. Link to comment Share on other sites More sharing options...
Nickel City Dude Posted December 1, 2020 Author Share Posted December 1, 2020 I went out again today because yesterday I was rushed and was unable to shoot all the cartridges I wanted. I fired some more today and had several FTF. I gave up and went home disappointed. I studied the guns very carefully and discovered that when I lowered the hammer slowly it would sometimes bind a little at the half cock position. I figured that the binding was slowing the hammer down and causing the light primer strikes. That got me thinking, what is moving when the hammer is going forward besides the hammer itself? I decided that the hand that turns the cylinder might be the culprit. Uberti uses a coil spring instead of a flat spring that are on the original Colts and its clones. I took the back strap off the guns so I could look at the screw that holds in the post and spring for the hand. I backed them off so that they were flush with the frame and to my surprise the binding stopped. I made up some more bullets and will try them out again this Thursday. I will report back after I have tried them again. I hope I have found the problem. Link to comment Share on other sites More sharing options...

I know, I'm the odd one but I like the flat spring instead of the "mouse turd" and coil spring. Link to comment Share on other sites More sharing options...
Bailey Creek,5759 Posted December 2, 2020 Share Posted December 2, 2020 I had the retaining pin on the firing pin bend. Changed firing pins . Didn't help anything. Tookthem back out. Happened to move a pin out of the way it rolled. That is when i notoced it was bent. Put new pins in Fixed the problem. Link to comment Share on other sites More sharing options...
Nickel City Dude Posted December 3, 2020 Author Share Posted December 3, 2020 Adjusting the hand spring screw solved the problem. I put 75 rounds threw each of them and not a single problem. I have put them up for sale in the Classifieds section. Link to comment Share on other sites More sharing options...
