Agency Arms Drop-In Flat Faced Trigger is a huge improvement over the OEM Glock trigger. It has an incredibly short, crisp reset, and features an aluminum flat shoe with an OEM polished trigger bar and minus connector set to 3.5 lbs.
This model is compatible with Gen 1-4 of Glock 9mm, .40, and 357 pistols (expect 42 and 43). It has a gray finish.
