TANDEMKROSS TANDEMIZED Ruger Mark IV 22/45 Race Gun

The TANDEMIZED Race Gun is a Ruger Mark IV 22/45 LITE that leaves the TANDEMKROSS shop with the company's entire competition catalog already installed: Victory Trigger, Blast Pack fire control group, halo charging ring, Game Changer PRO compensator, Titan extended magazine release, Bolt Keeper extended bolt stop, Cornerstone and Accelerator thumb ledges, hiveGrip, and a fiber optic front sight, all built on a TANDEMKROSS aluminum grip frame. Owners report trigger pulls around 2.5 lbs. Buying the parts and doing the work yourself costs meaningfully less, but the Race Gun exists for shooters who want a proven Steel Challenge setup with zero bench time.

The 22/45 grip frame carries the 1911 grip angle, and the LITE upper keeps the package light with a 4.4 inch threaded barrel under the compensator. The receiver's Picatinny rail accepts a red dot mount, which is how most buyers run it in Steel Challenge and NSSF Rimfire Challenge. Two 10-round factory magazines, a TandemKase pistol bag, and a cable lock ship in the box, and TANDEMKROSS covers its components against mechanical failure.

This is a serialized firearm sold only by TANDEMKROSS. It ships to your FFL dealer, transfer fees are the buyer's responsibility, and TANDEMKROSS does not ship it to California, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Washington, or Washington DC. Every upgrade on the gun is also sold separately, so an existing Mark IV can be brought to the same spec one part at a time.
