The Ruger Mark series has been the most popular .22 pistol ever sold. Millions of these have been produced, from the MK I all the way up to the MK IV. One of the beautiful things about the MK IV is it makes disassembly and reassembly much easier, which has traditionally been a vein for the Ruger Mark series. But with everything, there are improvements when you have production calls to try to keep it as low as you can, and yet have a good quality, reliable firearm. 

That’s where Volquartsen comes in. They make the best, most reliable aftermarket parts for your Ruger Mark series pistol and they are world renowned. Today we’re going to take a look at their Accurizing Kit for the MK IV. Not only does it really improve the trigger pull, which is exceptional, but it includes parts that really upgrade the pistol in other aspects.

We’ll take a look at the parts comparisons. I mean, Volquartsen really has world class parts, and not only does it make the trigger pull better, it actually aligns it better and it gives you better reliability. Even with this MK IV I’ve had a few issues with reliability. Once I installed the Accurizing Kit, they went away. We’re also going to take a look at replacing the ambidextrous safety on the right side of the firearm which was really easy to do. 

I want to thank Volquartsen for sending the Accurizing Kit to install in this MK IV.

Now, one of the things about this Accurizing Kit is that it’s the same trigger kit as in the Black Mamba. You’re getting a lot of the same features with your trigger, with the reliability that’s in the Black Mamba and honestly, for a fraction of the price. The Volquartsen Accurizing Kit for the MK IV will transform your trigger pull and it will also disable the magazine disconnect safety. It’ll just make it more reliable and built with much higher quality parts. 

We took the MK IV down to the range after installing the Volquartsen Accurizing Kit and it was absolutely flawless. I mean, the trigger pull was so much better. The parts we installed actually helped the gun to be more reliable as well. This kit will fine tune your MK IV. 

The complete drop-in kit comes complete with the CNC Machined Disconnector, Target Hammer, Hammer Bushing, Target Sear, Target Trigger with plunger and spring. It also comes with pre travel and overtravel adjustments.

The Accurizing Kit for the Ruger MK IV will provide a crisp, clean trigger pull. This kit will eliminate the magazine disconnect.
