Uberti 1873 Light primer strikes

[ucladude101]

So Long story short I have this 1873 in .357 magnum and it has light primer strikes 50% of the time. The thing is that I did take it into Jim Bowie at Cowboys and Indians shop and he hit something with a hammer he said than ran 3 flawless rounds through it. Now that certainly helped the problem but light primer do happen now like 10% of the time. Is there anything that I can do or hit something with a hammer that would help lol?

Any other work done to the gun to "slick it up"? Many times light primer strikes are due to a weak or revised mainspring, which has been changed/revised to lighten the action/trigger pull. And since they are leaf springs, they can also just wear out.

Some folks put a spacer under the leaf spring for lightened actions. It might be a washer at the mounting screw, or sometimes something like a little slice of an aluminum soda can, just in front of the screw (between the spring and the base of the receiver.

Also, what kind of primers are you using? If the action/leaf spring was lightened (or is wearing out) then you will definitely have issues with hard primers like CCI's.

"Hit something with a hammer" at the Cowboys and Indians shop? Well, these guys certainly know what they are doing with rifles like the '73. Maybe he could have removed the mainspring and hit it with a hammer a few times to bend it back into a "stronger" shape?

I would just buy a new mainspring - they are cheap and easy to install, and that could rule it out as causing light primer strikes. Make sure that you purchase a standard one and not a lightened one. If that fixes things but makes the action too stiff or the trigger too heavy, then you can make small changes to it until things feel better, but you still get 100% ignition (even with harder primers). Or you can lighten it a bit more and use softer primers only in that gun (like S&B or Federal).

This should solve the problem. From Long Hunter's site:

"There are three screws located on the lower tang of the rifle near the butt stock. The forward two screws are your hammer tension adjustment. Always start by tightening the rear screw first (also slightly larger than the forward screw) by about half a turn. This will increase the rifles hammer tension. Usually it only takes half to a full turn to get you what you need. CCI primers may require more than this to be reliable due to their highly inconsistent strike strength. Over the course of the rifles lifetime the hammer spring may get a little weaker. Once the rear screw has been tightened all the way and more hammer tension is desired. Simply move up to the most forward screw and start tightening it. This will further increase your rifles striking power."
