Volquartsen Ruger Mark IV 22/45 Upgrades


If you own a Ruger MKIV 22/45 Lite pistol, then you know what a great gun it is. You also know it doesn’t come with the best trigger in the world.  The folks at Volquartsen have been making Ruger firearms better for years so they figured they would add the 22/45 to the list.  They created a trigger kit and a compensator for the Ruger Mark IV 22/45 Lite pistol and the results are nothing short of amazing.

The 22/45 Lite pistol is a beautiful gun, both in looks and in firing. Ruger improved their pistol design by giving it a one-button takedown feature, making cleaning much easier compared to past pistols.  It has a precision molded polymer grip frame and a lightweight, ventilated aluminum receiver.  The grip panels are 1911 style which make them comfortable and easy to change out to a myriad of styles.  The target sights are very accurate and the installed Picatinny rail makes it easy to mount an optic.  My gun is a Black Hills Ammunition limited edition model with custom wood grips and a matching leather chest holster.  I added a HiViz green fiber optic front sight and a Burris Fastfire 3 red dot sight.  As good as all of this is the trigger was clearly the weak link.

I started by installing the Volquartsen Pistol Competition Kit. This kit includes the accurizing kit and the bolt tune up kit.  The accurizing kit is completely drop in and includes a new CNC machined disconnector, target hammer, hammer bushing, target sear, and target trigger with plunger and spring.  If you are handy with tools and working on guns then the kit isn’t too difficult to install.  If not, then take it to a gunsmith or send it to Volquartsen directly.  After about an hour I had it installed perfectly and the trigger was now crisp and clean and broke at just about 2.5 pounds.  The bolt tune up kit includes Volquartsen’s Exact Edge Extractor and SureStrike Firing Pin.  These are said to eliminate light strikes and stovepipes.  They were easy to install and the gun ran flawlessly.

The Volquartsen compensator is a nice looking addition to the Ruger receiver.

Next up was the Forward Blow Compensator. This was very easy to install as you simply unscrew the thread protector from the pistol and screw on the compensator.  The point of installing a compensator is to reduce recoil and improve accuracy.  On the one hand, you may be thinking, “It’s a .22, how much recoil can there be?”  But any reduction in recoil will help in faster follow up shots and this can definitely be felt after adding this little gem.  The compensator features 16 machined ports that are all angled forward of the shooter.  This directs the gas and noise away from you making felt recoil and muzzle rise less.

The Gerber Crucial multi-tool and Browning Performance Rimfire ammo are great accessories to your .22 shooting kit.
