GM is the exclusive Ultra Low Mass Competition Trigger Group . The result is an extremely lightweight hammer, sear, disconnector, hammer strut & pin that dramatically decreases lock time. This light weight combined with changes in geometry allows for lighter trigger pull weights. All of these benefits have made GM Engineering the most widely used by 1911, 2011 & Clones in competition today.
The Ultra Light Competition Trigger Group is CNC machined from tool steel and heat treated to hold your trigger job longer. Engagement surfaces are all precision machined and pre-polished. This part should be installed by a competent gunsmith. This hammer fits 1911/2011 style pistols.
