These Trigger Pull Kits include the Ed Brown parts needed for superior trigger function. The machined-from-barstock hammer features a long list of custom modifications for a match-quality trigger pull without a lot of work. Sear hooks are cut to height, then precision surface ground so just a light stoning is all that's necessary to achieve a crisp, clean-breaking trigger pull. Half-cock notch is narrowed to help prevent sear damage and pin holes are CNC-machined for location; lowered strut pin hole reduces full-cock spring pressure. Narrowed spur minimizes slide drag; larger-than-factory, Commander-style opening reduces weight for a fast fall and even faster locktimes. Fully-chamfere Mfg: Ed Brown
