 Light weight firing pin extension for model 73 rifles
$40.00

Fits Uberti model 73 rifles made before Jan. 2008

This firing pin extension is made from steel rod that has had a hole drilled through the center from the firing pin side to where the contour is machined on the hammer side. A plug is then pressed into the  end, and the machining is completed. The result is a firing pin extension that is 40% lighter than       the original. This lighter weight allows more energy to be transfered from the hammer to the firing pin. It allows you to have more reliable firing with a lightened hammer spring.
