Ruger Mark IV: Thoughts on Volquartsen Comp. bolt

Post by unbezwingbar on Thu Feb 01, 2018 1:22 pm

Hi Everyone,

I'm new to the forum, and Bullseye shooting in general. I purchased a Ruger Mark IV series pistol back in November, and I keep getting FTF and stovepipes when I shoot. It seems to be at least twice a match, during our weekly league, and once every 50 rd box during practice. I'm considering getting a Volquartsen competition bolt to help alleviate the issue, and wanted to know if anyone has some good advice/thoughts they could share.

Some information:

  • I have ~1,500 rds fired through the gun
  • I only use CCI SV in match, and for practice
  • I clean the gun after every use session (thank you, Ruger Mk. IV takdown feature!)


Thank you for your help!

Volquartsen bolt is basically a copy of the Ruger bolt with a different knob on the rear and has his extractor.
Get a Volquartsen extractor and you might need feedlips on your mags bent closed slightly to better control feeding. This is what I would do if it were mine.

Have you disassembled and thoroughly cleaned the magazines?I've found that the preservative stuff that Ruger puts on/in them will get sticky and cause all kinds of weird problems.+1 on Jon's opinion of the bolt and extractor.-Mike

Replace extractor with VQ before doing anything else. Ruger extractors are typically junk and won't last beyond a few thousand rounds anyway. Otherwise it's a great shooter for the price.

Is the issue universal with all your magazines?  18 yrs ago, I had the same issue with one of mine, albeit not even close to your frequency. I tried this fix on my mags & it solved the stovepiping.

May or may not be your cause, but it may be worth checking out.

A few guys at the club like the Mexican stuff in hard ejecting pistols, they say it’s a tiny bit shorter in overall length compared to American ammo and that seems to make the difference.
