Hammer coil spring system for Uberti Mod. 1873 and Uberti Mod. 1866
In additional to the trigger kit, here is the hammer coil spring system with stainless steel hammer. Made specially for Federal 100 primer. A second spring is added for Winchester primer. Minor modification on the butt stock needed.
New improvement on 2nd gen is the adjustment screw for the sear.
Hammer is completely through hardened. Hammer strut is made from spring steel.
When installing, take care that firing pin and firing pin extension move totally free, when breech block is closed. Otherwise energy is going lost between hammer and primer.
Best performance together with SBGW Trigger Kit.
This hammer kit can be used also with Uberti mod 1866.
This kit requires fitting by a competent Gunsmith.
