Best FN PS90 Forced Reset Triggers 2026

A forced reset trigger uses the firearm's cycling action to mechanically push the trigger forward into reset after each shot, instead of relying on the trigger-return spring alone. Every round still requires its own deliberate trigger press, which is exactly what keeps the system a semi-automatic trigger: one press, one round. The mechanism just removes the slow, sloppy finger-reset between shots and replaces it with a positive mechanical reset driven by the gun's own cycle. The result feels rapid, but the shooter, not the trigger, fires each shot.

On the PS90 the two reset-class options implement this differently. The Dorin XPRT90 is a true FRT: it swaps the factory semi-auto trigger pack for a factory-style replacement with nitrided 17-4 stainless reset components and a three-position selector whose third position is a dedicated Forced Reset mode. The Duality Arms RATL-R is a drop-in reset-assist system the maker positions in its KRISS Vector RATL-R lineage; it adds the same third selector position and speeds the reset, with its reset behavior labeled as vendor-stated rather than independently tested. Both are distinct from the Dorin billet shoe and the Promoted Pawn Creep Killer and spring, which improve trigger feel but do not add any forced-reset behavior. To go deeper on how forced-reset selectors and FRTs actually work, read our Super Safety guide, and for the neighboring non-AR forced reset landscape on the roller-delayed 9mm, see our MP5 forced reset triggers guide.

Buy the Dorin XPRT90 ($450) if you want the real forced-reset experience and you are willing to pre-order for the September-October 2026 production run. It is the only PS90 trigger with a dedicated Forced Reset selector position and premium 17-4 nitrided stainless internals, and it installs as a drop-in trigger-pack swap with an included jig. It is not compatible with full-auto registered PS90 trigger packs.

Buy the Duality Arms RATL-R ($250) if you want reset-assist speed shipping now for less. It is a drop-in system with a 7075 aluminum assembly that installs with no modification to the factory fire control group, ships on a one-to-two-week window, and bundles a 30-to-50-round magazine conversion insert so you can run your existing 30-round mags at 50-round capacity. Its reset behavior is vendor-stated rather than third-party verified, and like the XPRT90 it is restricted in a long list of states.

Buy a feel upgrade if you do not want reset speed or legal questions. The Dorin billet aluminum shoe ($100) replaces the soft factory polymer trigger with a rigid 6000-series billet aluminum shoe in a five-minute drop-in that does not alter fire-control operation. The Promoted Pawn Creep Killer ($70) is the cheapest meaningful in-stock improvement: an insert that removes pre-travel slop and lateral play and shortens the reset, with the Reduced Trigger Weight Spring ($50) as a follow-on that lightens an existing Promoted Pawn Delta Trigger. The two in-stock starting points are the RATL-R and the Creep Killer. Build out the rest of the gun in our rifle builder, and for the wider 5.7x28 ecosystem the PS90 belongs to, our 5.7x28mm pistols guide covers the handguns that share its cartridge.

A reset-assist or forced-reset trigger empties magazines fast, so PS90 magazines are the highest-ROI companion buy and the thing to handle before your first range trip. The PS90 runs proprietary top-mounted 5.7x28 polymer magazines that are not interchangeable with any other platform, so plan on buying genuine FN-pattern PS90 mags specifically. Buy a few 30s or 50s for the range, more for serious use, and keep a 10-round mag on hand for capacity-restricted states. Owners of the Duality Arms RATL-R get a head start here: it bundles a 30-to-50-round conversion insert, so an existing pile of 30-round mags can run at 50-round capacity.
