volquartsen mark II bushing

I have a Ruger Mark III 22/45 and have a question. I have a volquartsen sear and a Volquartsen markII hammer bushing to remove the mag disconcect my question is should there be a little washer in there also with the mark II bushing or is it not needed.

No washer. No need!

Thanks I though a smaller washer would clean up the little bit of slop in there.

From what I understand, and have gleaned from some posts on Rimfire Central, the sideways slop is not a factor. As long as you have little to no slop in the hammer pin to bushing fit the bushing should be good. From what I see, when the bolt is inserted the hammer positions itself correctly in the slot and negates any sideways movement.

As long as the outer diameter flange contact the widest part of the hammer no washer is need. If it does not you will need to use a spacer. If I recall it should contact the widest part of the hammer just a little. Since it is floating it's act the same as the original bushing/sleve.

Personally I prefer the friction fit of the Clark bushing. It's the only way to remove the creep in the trigger.

I have the Voquartsen Mk II bushing in my Mark III. Maybe I'm a neatness freak, but I have a M5 stainless washer in my hammer recess. I felt that would put an even load against the bushing flange, so it would wear evenly.

That, and the LCI plug, are my only mods. Sear, hammer, trigger, etc. are all factory, and I'm good with that.

I may be adding a washer to mine. I was at the range this weekend and I started having trigger issues. My MKIII has the LCI removed and replaced with a filler and I did the MKII bushing swap to get rid of the mag safety. After my 2nd box of cartridges I started having problems with the trigger not resetting.
I'm not sure if it's due to the slop in the bushing or if it's related to something else? There are no other mods to my pistol, stock sear, hammer, trigger.
Anyone have any ideas?

May want to check your trigger plunger for binding. Bullseye talks about polishing this and enlarging the hole. Another thing to check is to see if the disconnector is not binding against the frame. If placed in the gun without the hammer it should run straight or slightly toward the hammer. Mine was warped/binding against the frame. I used a small hammer to flatten it out. Also check for burrs that can cause binding.

My guess is that the VQ bushing is a tighter fit than the factory sleeve. Which should have taken some of the slop out. If the fit is not too wide you could try epoxying the bushing into the hammer. I know of a few that used loctite and epoxy. I have not heard any feed back as to how this has held up.

My VQ bushing does seem tighter than factory. I don't think my washer addition makes a huge difference, but there isn't much hammer cotnacting the flange, so the washer gives more surface area. I've got maybe 600-800 rounds with the VQ and washer, and no hiccups.

May be too, M5 washers from different sources would be a bit different. Mine seemed exactly the right thickness and diameter to match the hammer recess, but I had to just barely file the hole to fit the bushing.
