The Sig Sauer P365 Flat Trigger Kit (brand part number KIT-365-FLAT-TRIGGER) is a black factory-made direct replacement for the P365, P365X, and P365XL’s stock curved trigger. Sig Sauer’s flat trigger design lowers the finger’s contact point on the trigger face, increasing leverage for a pull that many shooters find smoother and more consistent than the factory curved profile. Because installation requires disassembly beyond a standard field-strip, Sig Sauer specifies that only certified Sig Sauer armorers install this kit as a full unit; substituting individual parts or improper installation can cause malfunction or void the firearm’s warranty. It’s a genuine factory upgrade for P365-family owners chasing a different trigger feel, best installed by a qualified armorer.
