The Sig Sauer P320 Flat Trigger (brand part number TRG-320-FLAT-BLK) is a black factory-made direct replacement for the P320’s stock curved trigger, built with a 90-degree break. 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 part; improper installation can cause malfunction or void the firearm’s warranty. It’s a genuine factory upgrade for P320 owners chasing a different trigger feel, best installed by a qualified armorer.
