Volquartsen trigger screw lengths? AND new VQ stuff

Post by ruger22 » Thu Feb 14, 2013 8:27 pm

The forum is pretty quiet, so I'll wake it up with a technical question!

I found this thread on Volquartsen triggers, and Bullseye's post on the trigger screw locations, the shorter screw being in the trigger face. I wanted to reassure myself that I had the screws correct:

( I have the newer stainless steel trigger, if it matters)

I reset and re-Loctited my overtravel today, just to be ready for Spring. When I first installed it, I noticed that the screw was in only about 60% of the trigger thickness when adjusted. In other words, the top 40% of the hole is empty. The hole is countersunk, so I only see two threads above the screw.

I have an extra screw set from VQ, so today I tried the longer pretravel screw in the trigger face. It is slightly above the face when adjusted, you can feel it on your finger. So it is slightly too long.

Would there be any benefit to using the longer screw, filed a bit?

FWIW, I set my overtravel with a feeler gauge. It will fire with a .005 leaf under it, but not a .010.

I also noticed today that VQ has new things I wasn't aware of, like a VQ design mainspring housing, a CNC machined stainless disconnector, a magazine loading latch, a spring loaded base for ejecting 22/45 mags, and a competition Mark bolt. Other new stuff, check it out.

The original problem with the VQ set screws was they were too short and when adjusted left only one or two threads in contact with the trigger body. This meant not enough holding power, even with thread locking sealant to maintain the adjustments. VQ started using slightly longer screws to compensate. If your engagement is 60% of the threads you are more than good and longer screws will not provide any better holding power for the adjustments.

Thanks. I thought I remembered something about an early problem with screws. Probably get them in standard sizes from a supplier, making their own screws may not be cost-effective for them.

My slightly short of perfect screw has done fine for over two years, I just redo it once in a while to clean it up. The countersink and threads pick up a bit of crud over time. Having a fresh adjustment can't hurt, either.

ruger22:

I really like the looks of the new Volquartsen disco with the round pin riding on the trigger plunger. However, I very gently rounded the trailing corner on the tab of my original design discos and can't see the need to invest in a new one.

I too have a few "too-short" screws for the triggers. Anyone know the size and where I might order a few longer ones?

If you need longer screws just call Nic or Scott over at Volquatsen Custom and they'll send you a couple of the longer pretravel screws.
