TANDEMKROSS Victory Trigger (Ruger Mark IV 22/45)

The Victory Trigger swaps the curved factory trigger on a Mark IV 22/45 for a flat, textured shoe. TANDEMKROSS's argument for the flat face is leverage rather than spring rate: a flat face lets the finger sit lower on the shoe, further from the pivot, which increases mechanical advantage and lowers perceived pull weight. The company is explicit that actual pull weight does not change. The flat face also gives a repeatable index, so a pull that drifts left or right is obvious instead of being hidden by a curved shoe that lets the finger slide.

Both travel stages adjust. Pre-travel and over-travel are set with Allen screws, and two lengths of each screw ship in the box so the shoe can be tuned to a specific frame rather than fought with one fixed length. Because the hammer and sear stay factory, this is the cheap half of a trigger job. Shooters who want the pull weight itself to drop need the Ultimate Trigger Kit, which pairs this shoe with the Thunder Hammer and Lightning Sear.

Fitment is grip-frame specific and TANDEMKROSS draws the line hard. This part number covers the Mark IV 22/45, 22/45 LITE, and 22/45 Tactical, plus the Mark III, Mark III 22/45, and Mark III 22/45 LITE. The page states that it does not work with any of the standard Ruger Mark IV pistols; the steel-frame Target, Hunter, Competition, and Tactical models use a separate part number. Black, red, and gold anodize are cosmetic.
