VQ trigger won't release Mark II sear

[JumboJVT]

Put a Volquartsen accurizing kit (trigger, sear, hammer, etc) in my early 90's Ruger Mark II yesterday. Installation went as expected, a little fussy, but no issues. Upon completion, the trigger/discconector barely moved the sear, such that pulling hard on the trigger (10+ lbs) would release the hammer if I applied enough force to the rear of the hammer: no free swing like the stock parts.. The gun did fire, but with the 10# pull. Note the trigger pretravel and overtravel screws were backed all the way out, so had no impact on anything.

So I started swapping the stock and VQ parts around (I'm now really good at Mark II internals!) and the verdict is that it's the trigger. Everything works fine with the balance of the VQ parts and the stock trigger: 2.3#s, and crisp and the stock parts won't work with the VQ trigger. Darned if I can see what geometries are different, but they obviously are. Since limiting pre- amd overtravel is a big part of the point of the kit I want to make it work.

I've been doing some interweb research, but I don't find anything right on point. But I do see reference to disconnector tolerance issues being the cause of many VQ kit related troubles, at least in later models. And it just makes sense with what I can see NOT happening when the the trigger is pulled. I plan to call VQ tomorrow, but has anyone here had a similar experience? Did a disconnector fix it? Thanks.

My first and only attempt at working on a MKIII was deleting the LCI and the safety that won't allow the gun to fire without a magazine in it. My route for the process was getting the MKII style hammer and bushing and going ahead and installing the adjustable trigger. I never made it to the trigger part, as the hammer and bushing were such a tight fit they'd barely move. I tried and tried, but finally gave up.

It ended up going to a gunsmith and getting the whole VQ accurizing kit...he showed me with a set of calipers how the VQ parts I ordered were not the same spec as the ones in the kit he got.
Manufacturing errors in your parts? Apparently it is possible...

Does make one wonder, as most all of the troubles corrected with the disconnector that I've been reading about were on the later models. We'll see what VQ says.
