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!
