Mount On Outside; Save Repeated Assembly/Disassembly
Precision-ground and hardened trigger and hammer pins (.0005"
tolerance) that mount on the outside of the gun frame, using the
gun's own pin holes. Allows you to easily observe and adjust
trigger pull and sear engagement without repeated
disassembly/reassembly to "blind test" changes. Saves time and
money; greatly improves chances of getting it right!
