Best trigger for Ruger Mark IV

by Tom B, Gear Expert from IL, United States Written on July 28, 2021
The Volquartsen competition kit for the Ruger Mark IV is awesome! This kit is super easy to install and has a huge positive impact on trigger function. Before installing the kit my trigger was mediocre at best. I also had some extraction issues. After installing the kit my trigger is super light and I have had zero issues with extractions. Highly recommend for anyone looking to improve the performance of their Mark IV.
Most Helpful Positive Review Night and day!
So first let’s talk install difficulty. For non professional gunsmiths. If a Glock drop in trigger is a 2 out of 10 in difficulty, this install is a 6-7 out of 10. A lot of parts to keep track of. I will say, the instructions are good. YouTube helps too. Now there is one major problem that many have run in to with this project. This problem is Ruger’s fault. The safety lever screw, where the removal is one of the first steps in this job, is overtightened from the factory. The torque on this screw along with the supplied 1/16 allen causes a round out almost immediately. I had to do some ...

Great Trigger!

by bp, Verified Owner from PA, United States Written on May 20, 2025
Dropped this trigger in 2 guns. Super easy install and great precision with the pre and post travel screws. Not long to dial in the pre and post travel screws as well. Definitely recommend to anyone looking for an inexpensive option to improve their 22 trigger!

Buttery Soft

by KCDawsonville, Verified Owner from GA, United States Written on April 20, 2025
This trigger is everything that I expected. The install can be technical at points, but overall straightforward. Love this mod for the Mark IV. The pull is smooth and presets can micro tune for your preference.

Well worth the money!

Night and day improvement

by Pocono Joe, Verified Owner from PA, United States Written on August 15, 2024
My Ruger Mark IV 22/45 needed improvement to it's factory trigger. The factory trigger needed way too much pressure which was detrimental to my target grouping. After installing the Volquartsen Competition kit, trigger pull was not only cut in half, but it is now smooth as silk. After watching the Volquartsen installation video several times, I did the swap. This was my first trigger job and it worked out great. The Competition kit also included a new extractor and firing pin. I definately recommend this upgrade. It was worth every penny. Optics Planet is awesome too. The price was great and the free shipping was fast.

Perfect pull with alot of adjustment for personal liking

by DMac, Verified Owner from AZ, United States Written on August 14, 2024
Installation can be tricky in mk4 22/45, watch every video you can find. Trigger pull is consistent and light. You can adjust the pre travel big or small. Great set up.
Best Used for:
  • I use mine for small game

Huge improvement.

by Tor, Verified Owner from CT, United States Written on May 14, 2024
This kit is far superior to tandemkross, the part fit and finish are unmatched. My 1st trigger installation on a pistol and it went very smooth thanks to Volquartsen installation video. No fitting of parts was required and pre/over-travel adjustments were simple and have held firm for over 1000 rds so far. Definitely a lighter pull weight but the most noticeable difference is the clean sharp break and short reset vs the OEM gritty rolling break and long reset.
Pros:
  • Quality
  • improved accuracy
  • Improved trigger pull
  • Ease of insallation
Cons:
  • Need one in every Mark IV
Best Used for:
  • upgrading trigger pull/accuracy
Would recommend: Yes
