The Brownells Trigger Adjustment Pins are made from precision ground M2 tool steel, hardened to Rc 55-60 to last a lifetime. These pins mount on the side of a 1911 frame and allows the user to easily observe and adjust trigger pull and sear engagement without repeated disassembly/reassembly to 'blind test' changes.
