Questions & Answers
Does this kit work with the Mark IV Hunter stainless? Expert Answer

Yes, this will work in Mark IV pistols as well.

by Ethan C., Gear Expert, January 17, 2019
Will this kit work on a Mark 4 competion and is it something a novis can instal or do you need a master gunsmith? Expert Answer

Yes, item VC4AK and VC4AK-ST will fit your gun. We recommend having this installed by a qualified gunsmith, but if you are familiar enough with taking apart and re-assembling firearms, you should still be able to do it yourself.

Helpful Positive Review Works great but a little tricky to install yourself by Eric, December 18, 2020
Dramatically improved the weight of the trigger and the accuracy of the gun. Can tell a real difference when dry firing with snap caps with my red dot sight. Assembly is not as easy as they make it out to be and I had to get a little help with one of...

Helpful Positive Review Amazing difference by FLDave, June 22, 2021
I recently bought a new Ruger Mark 4 22/45 Target as a cheaper compliment to shoot to my 9mm's. A group of guys that all shoot various Mk4's recommended the Volquartsen kit so I ordered a stainless one, didn't need stainless but the bright trigger l...
