VOLQUARTSEN | RUGER MARK IV COMPETITION UPGRADES
A Flat 90-Degree Break. The Complete Volquartsen Upgrade.
The Volquartsen Pistol Competition Kit with Gold 19.22 Flat Trigger brings a crisp 1.75 lb trigger-pull design, a short, positive reset, and precision bolt components to your Ruger MK IV. With Volquartsen's complete Accurizing Kit and Bolt Tune-Up Kit in one Made-in-USA package, this is a premium upgrade you can feel with every trigger press.
The trigger is the connection between you and the shot. Volquartsen's 19.22 Flat Trigger delivers a different kind of control: a broad, flat face, a distinctive 90-degree break, and the quick reset competitive shooters appreciate. Finished in matte gold anodizing, this version gives your Ruger MK IV a standout look without sacrificing the refined mechanical feel that built Volquartsen's rimfire reputation.
And because this is a Competition Kit, not simply a replacement trigger shoe, it includes the precision-machined internal parts and bolt upgrades to carry that attention to detail through the pistol.
The 19.22 Flat Trigger: Built for a Lighter, Cleaner Break
At the heart of the kit is the Gold 19.22 Flat Trigger, working with Volquartsen's Target Hammer, Target Sear, CNC-machined disconnector, hammer bushing, and supporting components. Volquartsen designed the flat-trigger combination around a 1.75 lb pull, with a clean 90-degree break and short, positive reset—an especially appealing combination for steel matches, precision target shooting, and high-round-count practice.
The trigger assembly includes pretravel and overtravel adjustments so the movement can be refined to suit the shooter. The hammer and sear are wire EDM-cut from A2 tool steel, reflecting the quality of the parts you don't see as much as the trigger face you do.
Volquartsen Performance Goes Beyond the Trigger
The included Bolt Tune-Up Kit adds Volquartsen's Exact Edge Extractor and SureStrike Firing Pin. Together, these components target positive case extraction and consistent rimfire ignition—an excellent complement to a lighter, more responsive trigger.
The Ruger MK IV aftermarket includes familiar names like Tactical Solutions and TANDEMKROSS. For shooters who want to upgrade the trigger system and core bolt components as a coordinated package, Volquartsen's Competition Kit brings its proven precision-component approach together in one box.

Frequently Asked Questions
Flat versus Target Trigger, complete-kit contents, MK IV compatibility, and genuine Volquartsen upgrades.
What makes the Gold 19.22 Flat Trigger different?
The 19.22 has a flat trigger face with a crisp 90-degree break and short, positive reset. Volquartsen designed this Competition Kit for a 1.75 lb pull. It's the option for shooters who want a lighter, flatter trigger feel with the premium gold finish.
Is this the same as the Volquartsen Gold Target Trigger kit?
No. This kit uses the Gold 19.22 Flat Trigger with a 1.75 lb design. The Gold Target Trigger Competition Kit uses Volquartsen's classic curved Target Trigger with a 2.25 lb design. Both include the same broader Volquartsen trigger-system and bolt upgrades, so choose the trigger shape and feel that suit you best.
Does the Competition Kit include the extractor and firing pin?
Yes. The included Bolt Tune-Up Kit provides the Exact Edge Extractor and SureStrike Firing Pin. You get the complete trigger-system upgrade and these premium bolt components together—no separate Bolt Tune-Up Kit purchase needed.
Will this fit my Ruger MK IV 22/45 or 22/45 Lite?
Yes. Volquartsen designed this Competition Kit for factory-frame Ruger MK IV, MK IV 22/45, and MK IV 22/45 Lite pistols. It's the modern MK IV trigger system, with the flat-trigger configuration made for that platform.
Should I buy the Competition Kit or just the Accurizing Kit?
Choose the Competition Kit when you want the full Volquartsen upgrade: fire-control components plus the Exact Edge Extractor and SureStrike Firing Pin. The Accurizing Kit is focused on trigger performance. For a complete MK IV refresh, the Competition Kit brings it all together.
Does installing the kit change the magazine disconnect?
Yes. The Accurizing Kit removes the MK IV factory magazine disconnect, which means the pistol can fire with the magazine removed. It's an important functional change to understand when handling the pistol; follow Volquartsen's installation and safety instructions.
Is Pete's Pillars an authorized Volquartsen dealer?
Yes. Pete's Pillars is an authorized Volquartsen dealer. We carry genuine Volquartsen Competition Kits, Accurizing Kits and premium Ruger Mark Series parts, so you can build your pistol around the quality Volquartsen is known for.
