Volquartsen Accurizing Kit for Ruger MK IV Pistol – Black Trigger VC4AK

Description

The factory trigger on a Ruger MK IV is fine for casual plinking, but if you want to shrink your groups and shoot to the pistol's real potential, the trigger is the first thing worth addressing. Volquartsen's Accurizing Kit is a full drop-in package that replaces the internals responsible for how your trigger feels, giving you a crisp, clean pull right around 2.5 pounds with adjustable pretravel and overtravel so you can dial it to your liking.

This kit fits every variation of the MK IV, including the 22/45 and 22/45 Lite. If your pistol says Ruger Mark IV anywhere on it, this kit will work. It also does away with the magazine disconnect, so the trigger feel stays consistent whether or not a magazine is seated.

What Sets the Volquartsen MK IV Kit Apart

Volquartsen has been building precision rimfire parts out of Carroll, Iowa for over 40 years, and that attention to detail shows here. The hammer and sear are wire EDM-cut from A2 tool steel, which is what gives the engagement surfaces that glass-rod break folks talk about. The complete kit includes a CNC-machined disconnector, target hammer, hammer bushing, target sear, and a target trigger with its plunger and spring. Everything is built to tight tolerances rather than mass-produced, which is why the results feel so repeatable.

Installing the Ruger MK IV Accurizing Kit

This is a hands-on upgrade, and plenty of owners tackle it at the kitchen table using Volquartsen's online instructions and a few YouTube walkthroughs. Take your time, lube the pivot points as you go, and don't rush the pretravel and overtravel adjustments. Owners regularly report pull weights landing between 1.6 and 2.5 pounds depending on how they set the screws, with a noticeable bump in accuracy and consistency at the range. It is a straightforward job for anyone comfortable detail-stripping their pistol, and the payoff is a trigger that feels like a completely different gun.
