Do Mark IV Triggers "Break In?"

Do Mark IV triggers improve as they "break in?" I got a chance this week to shoot two different models at the range. I was very impressed with both pistols. One was the basic blued Target model, and the other was a Competition.

Both guns had excellent fit and finish. I enjoyed shooting both pistols, and could shoot well with them.

One thing that did stand out for me, however, was the triggers. Neither Trigger had any creep or grit, or anything like that, but both were substantially heavier than I expected.

One of the owners already has a Volquartsen kit on order, so I guess we won't find out if his stock trigger would get better with use.

Has anyone here had their stock Mark IV triggers get better as they got broken in?

I have the Mark IV 22/45 lite. My trigger was an horrendous 5 pounds 14 oz and felt like I had to break through the safety on every shot. I fired about 3000 rounds before my Volquartsen Trigger Kit came in.

There was no difference during break in. The VQ kit brought the trigger pull down to 2 1/2 pounds, no creep and broke like a glass rod. After some more work and a Tandemkross trigger the pull is now 1.5 lbs and I'm very happy. May be too light for some people but I like my autos to be that weight for competition.

Do Mark IV Triggers "Break In?"

I installed The Volquartsen sear and hammer yesterday but not the trigger, and the factory trigger works great with just a little over an 1/8 inch take up. The sear and Hammer is over ninety percent of the trigger pull weight.

The trigger improvement during break in is only due to the rough sear and hammer notch grinding each other a bit smoother through repetitive rubbing. The amount of improvement will be quite small through thousands of rounds.

The VQ sear has a slightly less positive engagement angle, and is light years better polished. Replacing the factory sear and smoothing the hammer notch will give awesome trigger improvement right away. Even years of break in can never match the improvement.

Mine new was at 4.5 pounds. After about eight hundred rounds, it pulls about 4 pounds now.

I installed the Volquartsen Accurizing kit in my Target model. I think I have maybe 300 rounds through it since and I think it is breaking in. Had a few failures in the beginning but it seems to be working great now.

Did you shoot it stock first? If so, how much of a difference has the Volquartsen kit made for you?

VQ Trigger

Yes, I shot it a lot stock before I installed the Volquartsen Accurizing kit. Made a big difference. I do not have a trigger pull gauge, but it is close to half of what it used to be. Light and crisp.
Seems the more I shoot it, the better it gets. Installing the kit is challenging, but doable and worth it. As for break in, it seems to be getting better the more I shoot it.
