VOLQUARTSEN | RUGER MARK IV COMPETITION UPGRADES
A Bold Red Trigger. A Serious Competition Upgrade.
Give your Ruger MK IV the crisp, confident feel of Volquartsen's Red 19.22 Flat Trigger and the precision bolt components to match. This Made-in-USA Pistol Competition Kit combines a trigger system designed for a 1.75 lb pull with Volquartsen's Exact Edge Extractor and SureStrike Firing Pin—an upgrade you can feel with every shot.
A premium trigger should feel as sharp as it looks. The red 19.22 Flat Trigger brings a striking accent to a thoughtfully engineered Ruger MK IV build, but its real appeal is at the trigger finger: a clean 90-degree break, short positive reset and a flat face that makes precise control feel natural.
This is the complete Volquartsen Competition Kit—not just a new trigger shoe. By combining the MK IV Accurizing Kit and Bolt Tune-Up Kit, Volquartsen brings its trigger, extractor and firing pin upgrades together for the shooter who wants a well-rounded .22 LR target or competition pistol.
Red 19.22 Flat Trigger. Crisp Break. Fast Reset.
The 19.22 Flat Trigger is built around an immediately noticeable shooting experience. Its flat profile gives your finger a consistent contact surface, while the 90-degree break and short, positive reset bring the precise feel competitive rimfire shooters appreciate. Paired with Volquartsen's Accurizing Kit, this configuration is designed to deliver a 1.75 lb trigger pull.
Behind that red trigger is a carefully matched group of Volquartsen parts: Target Hammer, Target Sear, CNC-machined disconnector, hammer bushing and associated components. Pretravel and overtravel adjustments complete the premium trigger system. The finish adds character; the performance engineering is why you buy it.
The Bolt Gets an Upgrade, Too
The included Volquartsen Bolt Tune-Up Kit brings the Exact Edge Extractor and SureStrike Firing Pin into the same package. Designed to support positive extraction and consistent rimfire ignition, these premium components complement the refined trigger for steel matches, regular range sessions and high-round-count practice.
The Ruger Mark IV aftermarket includes respected manufacturers such as Tactical Solutions and TANDEMKROSS. When the goal is to refine the pistol's core trigger and bolt components together, Volquartsen offers a compelling combination of precision manufacturing, thoughtful design and a complete, matched upgrade package.
Build Your MK IV Your Way
Love the 19.22 trigger but want a different finish? Choose the Volquartsen Black Flat Trigger Competition Kit or Gold Flat Trigger Competition Kit for the same distinctive trigger feel with a different look. Prefer a classic curved trigger? Our Black Target Trigger Competition Kit and Gold Target Trigger Competition Kit use Volquartsen's 2.25 lb Target Trigger configuration.
Already have a trigger you love? Consider the Volquartsen Competition Kit without a Trigger. Or focus on bolt components with the Volquartsen Bolt Tune-Up Kit. For compatible MK IV 22/45 builds, the Volquartsen Extended Bolt Release adds another practical refinement. Find more genuine Volquartsen options in our Ruger Mark IV Parts & Upgrades Collection.
