Ruger Mark I, II, III, IV & 22/45 Pistol Trigger Shims

Ruger Mark II Trigger Shims

Our Trigger Shims install on the Left Side of the Trigger, between the Trigger and the #AN37 Bolt Stop Assembly.
Our Shims work with both Mark II, Mark III, Mark Iv and 22/45

Installing a Shim here will stop the Trigger from Rubbing the Frame on the Left Side, a Common Problem with this Gun.
The left side can have shims installed / stacked until the Trigger no longer contacts the Frame on the left side of the Trigger, and can take anywhere from a few to several thicker shims

Volquartsen VC3RS Recoil Rod and Spring Kit

fits MKI, MKII, MKIII, MK IV, and 22/45

Volquartsen innovative design makes it quick and easy to match your spring weight to your ammo of choice, greatly improving the performance of your pistol. It is so easy springs can be changed out in under 60 seconds!


Three springs are included in the kit, and are color-coded for easy identification:

  • It ships assembled with our bright-finish, standard rate spring. This configuration is a direct replacement for the Ruger KA-57 recoil assembly.
  • A gold, heavy weight spring, for high velocity ammo.
  • A dark-coated, reduced-power spring. This spring can be used for a softer recoil with standard velocity ammo. It can also be used with most subsonic ammo, but does not enable the use of 22 short or CCI Quiet ammo.

The standard rate spring is suitable for subsonic, standard and high velocity however you will see your best results using specific spring weights.


  • Recoil spring assembly is designed for a variety of pistols:
    the Volquartsen Scorpion, Ruger MKI, MKII, MKIII, MK IV, and the Ruger 22/45
  • Product Number: VC3RS
  • UPC: 810162014377
  • Made in the USA

VC3FB Magazine Follower Button

fits MKI, MKII, MKIII, MK IV, and 22/45

Have a sluggish MKII, MKIII, MK IV, or 22/45 Ruger magazine? Chances are the spring is fine but the actual culprit is the metal on metal contact of the magazine button.


Not only does this make magazines hard to load but it can also cause feeding problems by allowing the round to hang up before the bolt closes. If your magazine has a gritty and rough feeling when loading, I suggest using Volquartsens Magazine Follower Button for incredibly smooth operation. The button is knurled for easy gripping but more importantly, it eliminates the metal on metal contact providing easy loading and trouble free feeding

Testimonial on 30380 Kit:
I just wanted to drop a quick note to thank you for this kit. I installed this kit in my Old Ruger Standard Pistol ( 1958, not mark I ) and it transformed it from a plinker, to a full blown target shooter, capable of 1/2" 3 shot groups at 30 yards. People don't believe it until they see it shoot. Amazing kit and very little gunsmithing to make it work perfect. Whole job took about an hour with a little file work Thanks to you, this thing is a tack driver!....Literally! I was told by my buddy's it was just a fluke! No way! Great kit!
Thanks Very Much - Dave S.

Wolf High-Performance Target Loads

Click to go to Brownells Wolff .22 LR Ammo

This is the ammo I use and recommend.
Five round groups in one ragged hole are possible with this ammo at 50 yards benchrest, as I have done it.
It may not be as consistent as the $15 a box stuff, but it fits my pocketbook when I want to make holes in paper!
Wolf 22 LR target ammunition is loaded with VihtaVuori powder prized by centerfire benchrest shooters for its consistent burn rates. The high-quality brass is formed using a proprietary manufacturing technique that maintains outstanding round-to-round consistency to help deliver consistent pressures and superb accuracy.
This ammo is sold and shipped through Brownell's - click the picture to go to Brownell's Wolff Ammo Page.
