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 ...

Mark IV Volquartsen Upgrade

by Bigkuxdeluxe, Verified Owner from CO, United States Written on April 4, 2026
I recently installed the Volquartsen Accurizer Kit on my Mark IV, and the difference is night and day. The trigger break is crisp, clean, and consistent, with a much more predictable reset than stock. It immediately tightened up my groups and made the gun far more enjoyable to shoot, especially during longer range sessions.

The install was a bit intense, but the video provided on their website made it much more manageable and kept everything on track.

Overall, the component quality is exactly what you’d expect from Volquartsen; top notch. Easily one of the best upgrades you can make to this platform.

Not for Old farts

by Stateline, Verified Owner from TX, United States Written on February 25, 2026
I finally sent it off to Volquartsen for installation. I am 84 years old and thought I could do it, but my hands would not obey my commands. This unit has turned my Mk IV into a true target pistol.

Volquartsen Firearms MK IV Pistol Competition Kit

by Brad Johnson, Verified Owner from IN, United States Written on February 13, 2026
Best price I found, offset even more by accumulated OpticsPlanets bucks and very fast shipping.

As far as the product, I believe that this is the best investment you can make in Mark IV improvements. Well worth the cost and time.

Mark IV Upgrade

by Brad Johnson, Verified Owner from IN, United States Written on February 5, 2026
Optics Planet is my go to for anything that the sell; they have a very diverse product set, very good pricing, free delivery on most things, and excellent customer service.

I bought this kit to upgrade my Mark IV, it came quickly, was a better price than I could find anywhere, and they delivered quickly.

Thanks, OP.

Greatly improves trigger pull

by SCA, Verified Owner from MI, United States Written on January 28, 2026
Trigger upgrade: Reduced the trigger pull from 4.5 pounds to 2.25 pounds. Reduced my group size by 60%. A little tricky to install because of the small size of the parts and the limited space. I used a vise to hold the grip while doing the install. The extra "hand" was a definite help. There are several videos out there that show how to do the install that are better than the Volquartsen video ( but even that video is helpful.) Bolt upgrade: Can't tell if it improved anything or not. I haven't fired enough rounds yet to tell if I had any problems with soft strikes or failure to extract. I didn't realize it was part of the package (really just wanted to lighten the trigger pull). The extractor was the most difficult part, but not too bad with the vise to hold the bolt and letting me use both hands to manipulate the original extractor and plunger.
Pros:
  • Lighter and smoother trigger pull
Cons:
  • Tight spaces make install tricky
Would recommend: Yes

installing trigger kit.

by Warden, Verified Owner from PA, United States Written on January 22, 2026
It took me a little over an hour to install the kit. Trying to figure out just exactly where the sear spring went was problematic. The volquartsen video is good but they juice it up by spinning the parts around in circles as they are going in to place making it difficult to see just what is happening.
There are several good videos on line that are very helpful. I found installing the hammer the hardest part. You have to slide some of those parts together sort of above the receiver before you slide them into place.
Ended up with a nice trigger. Almost no creep, light pull and very little over-travel.
