SliX-Pin One-Piece MIL-SPEC Firing Pin for Uberti 1860, 1866 & 1873 Rifles

Improve the reliability of your Uberti lever-action rifle with the SliX-Pin One-Piece Firing Pin. Precision CNC-machined from high-strength MIL-SPEC alloy steel, the SliX-Pin is engineered to provide exceptional durability, more consistent primer ignition, and dependable long-term performance.

Firing pin
Scott edwards - 12/08/2025
Read the included instructions a few times, after understanding what was needed it was easy to dress the pin down to correct length. Works like designed
GREAT PRODUCT

The firing pin in my recently acquired M73 in 32/20 was blunt and flat faced. It also hit the primer slightly off-center. I did have to do some fitting of the OAL at the back end of the SliXsprings firing pin. With a small amount of work on the bolt, the firing pin indent is closer to center and the rounded end of the firing pin causes it to give a much better indent on the primer. The gun shoots well and I strongly recommend this firing pin.

SliXprings Firing Pin for Uberti Model 73 rifle
B&S Gunsmithing - 04/13/2024
I was replacing the "original" SliXprings firing pin that was from a noted "custom" gunsmith. On examination of the replacement I really expected the juncture of the pin itself to the "head" to have a more pronounced radius (larger)to eliminate the sharp edge stress concentration corner. This is exactly where the firing pin broke. This rifle was purchased used, evidently the original owner dryfired the rifle frequently.

I recommend this for all Italian 73's. Excellent quality
Great product.
Dutch - 06/13/2023
Replaced the original factory firing pin and spring after nearly 20 years of shooting. I was getting the occasional misfire even on Federal primers. Haven't had a misfire since installing the Slixspring pin and even shot some Fiochi factory ammo with no problem.

GREAT
Excellent Firing Pin
Steve P - 02/17/2022
This firing pin works great in my Uberti 1873 rifle. I had no issues installing it and needed no adjustments. I was able to open up the gun, slip out the old firing pin and drop this one in. This has a much stronger feel than factory. The pin is a little longer than factory giving it a more positive primer hit. Recommend this if you shoot fast and often.
