After putting many 100s of rounds down range, I can now say that my Mark IV works as intended, and very well. If I could shoot as well as the gun, I would be very happy. This is an excellent target/vermin gun and the breakdown for cleaning is super easy. The Volquartsen trigger and firing pin...

While that may be true, if you remove the firing pin from a mark III or II, you render the gun inoperable. That is it becomes a paper weight. I would rather have two operateing pistols. JMHT

Well, I finally got to the range to test the new firing pin. As my shop (gunsmith explained) it, the original Ruger firing pin has a hole in it that helps to lighten the whole gun but as a result, with the Volquartsen trigger parts makes for many light strikes on the rim fire ammo. With the...

Thank you all for your comments and suggestions. My shop, along with Volquartsen, have installed the Volquartsen firing pin and returned the Mark IV to me. I have not yet been able to get to the range to test, but in talking with many people, it does appear that this is one of the best...

It does seem that with the Volquartsen Sure fire Fireing pin that the MarK series guns now do function very well with the Volquartsen Trigger Kits installed. Maybe they should include it in the kits. Thank you br6ad for the update. When I talk with my shop tomorrow (CLOSED TODAY) I will...

While I agree with most of the suggested fixes, it seems that Volquartsen is aware of the firing pin issue (light strikes) and have notified my shop of the fix, (one of their Sure fire Firing pins) Putting many rounds through the Ruger is in fact a great idea, but with so many light strikes and...

br6ad, welcome. Your comments seem to mirror my issues. Hopefully the new firing pin will solve the problem. I won't know until I get my Mark IV back from the shop. If you would post your results of your tests it would be appreciated. Thanks.

I'm not sure I would go as far as wwb, but to his point, the trigger pull was about 6 lbs prior to the trigger job. And I suspect it will be very much smoother when the kinks are ironed out, with a crisp reset and a very clean pull.

teuthis, no offense taken. Everyone has the right to his/her opinion, for which I served and defended, albeit a long time ago. That being said, a little history. I purchased a Mark III some time ago, as a target pistol. The trigger pull was exceptable but, after some research and firing a...

Talked to and returned the Mark IV to the shop. They have contacted Volquartsen and there may be a slight issue with the barrel and firing pin with the trigger kit installed. The shop and Volquartsen are working to solve the problem. Update later. Thanks.

Thank you for the welcome. The trigger job was done by a local gun shop of which I have a lot of confidence. The trigger now has between 2.2 and 2.5 pull on my scale. The kit included a new sear spring, a new trigger spring and plunger, trigger, hammer, sear, trigger bar. The magazine...

i got a mark 4 and had the volquartson trigger job done. Now I am getting many (way to many) failures to fire. Prior to the trigger job, I put 100-150 rounds through it with no problem. Anyone else have this problem? I did change ammo with no improvement. The light strikes seem to fire in...

The manual that came with the pistol did not have the pin listed. The online manual did. I will call Ruger Monday. Thanks to all of you that responded. Much appreciated.

New member. I changed out the grips on my Mark IV and there was a small shouldered pin that seemed to fall out of the right side grip. Now I can't find it. Is it important?
