VOLQUARTSEN | RUGER MK II & MK III TRIGGER UPGRADES
A Stainless Trigger. A 2.25 lb Break. No Fitting Required.
The Volquartsen Accurizing Kit replaces the heart of your Ruger MK II or MK III fire-control system with a stainless steel Target Trigger, target hammer and sear, and a silver extended bolt release. Volquartsen rates the kit at a 2.25 lb pull, and it drops in with no stoning or fitting. Made in USA.
A MK II or MK III that shoots well can still feel held back by its factory trigger. Volquartsen's Accurizing Kit is the proven answer: a complete set of matched fire-control parts designed to work together, so the pistol breaks cleanly and predictably shot after shot. It's the upgrade bullseye shooters, steel competitors and serious plinkers reach for when they want a classic Ruger to feel like a precision instrument.
Precision Parts, Tuned to Your Preference.
The kit includes a target hammer, target sear, disconnector, the stainless Target Trigger with a trigger return spring and polished plunger, an extended bolt release, and Volquartsen's MK II hammer bushing. Pretravel and overtravel are adjustable, and medium-strength Loctite is included to lock your settings in place. Because the parts drop in without stoning or fitting, the upgrade stays approachable for owners comfortable working on their own pistol. Final pull can vary slightly with factory frame tolerances, which is normal for any drop-in trigger system.
Add the Bolt Upgrade or Go Complete.
Pair the trigger with Volquartsen's Bolt Tune-Up Kit, with its Exact Edge Extractor and SureStrike Firing Pin, for more positive extraction and consistent ignition. Or get everything at once with a Competition Kit: the Competition Kit with Black Trigger and Silver Bolt Release, the all-black VC2PCK-B Competition Kit, or the Gold Trigger Competition Kit. Ruger owners also consider names like Tactical Solutions and TANDEMKROSS; for a matched fire-control upgrade, Volquartsen remains one of the most established choices in rimfire.

Frequently Asked Questions
What's included, MK II/MK III fitment, the magazine disconnect, and ordering genuine Volquartsen components.
What's included in the VC2AK-S-ST Accurizing Kit?
A target hammer, target sear, disconnector, stainless Target Trigger with trigger return spring and polished plunger, a silver extended bolt release, Volquartsen's MK II hammer bushing, and medium-strength Loctite for the adjustment screws.
Which Ruger pistols does it fit?
It fits Ruger MK II and MK III target models and 22/45 models. In 22/45 installations, the extended bolt release and sear spring are not used. It is not designed for the MK IV.
Does it remove the MK III magazine disconnect?
Yes. On the MK III, the included hammer bushing removes the magazine disconnect, so the pistol can fire with the magazine removed. Everyone handling the pistol should understand that change. Volquartsen states this kit is its only recommended method for removing the MK III disconnect.
Is the trigger adjustable?
Yes. Pretravel and overtravel are both adjustable, and medium-strength Loctite is included to secure your settings. Volquartsen designs the kit for a 2.25 lb pull; final pull may vary slightly with factory frame tolerances.
Does it require fitting or stoning?
No. The kit is designed to drop in with no stoning or fitting. Follow Volquartsen's installation instructions and function-check the pistol before live fire.
What's the difference between the Accurizing Kit and the Competition Kit?
The Accurizing Kit covers the trigger and fire-control system. A Competition Kit adds the Bolt Tune-Up Kit—Exact Edge Extractor and SureStrike Firing Pin. See the VC2PCK-S Competition Kit for the complete package.
