Overview

The Dorin billet aluminum trigger replaces the factory PS90 polymer trigger shoe with a CNC-machined aluminum unit. The factory shoe is functional but uninspiring, with the soft polymer flex that any PS90 shooter notices on a long range session. The Dorin replacement adds rigidity and a crisper tactile break feel without modifying the underlying fire control group geometry.

This is a shoe-only upgrade, not a full trigger pack swap. The factory PS90 fire control group remains in place; the Dorin part replaces only the contact surface that the trigger finger operates. Drop-in install with no fitting required.

Currently out of stock at FN Specialties as of mid-2026. For PS90 owners who want a more dramatic trigger upgrade, Dorin's XPRT90 forced-reset trigger system is the premium alternative at $450.
