If your Ruger has a good, crisp, trigger pull, install the Volquartsen trigger. It has take up and over travel adjustments. I wish I had installed a
Tandemkross Victory trigger in my other MKII for comparison, I only recently found out about it. I would like to try a rough surface on the trigger face. I do prefer the Volquartsen extended safety and slide release to the factory versions.
I am going to pee all over the Volquartsen hammer and sear. I installed one and removed it. The trigger was better before. There was a lot of takeup and mush with the Volquarsten hammer and sear. It also took too long to install the things for me to attempt to file the surfaces to remove the creep. The first time I installed a Volquartsen trigger it took hours.
If you plan to replace the trigger, be certain to find a youtube video and watch it. Reassembly is not obvious, can only be done in sequence. I recommend placing a white sheet on the floor, wear an apron, and sit down. Springs and plungers will go flying and if you are standing up, they will go yards (hundreds it seemed) instead of feet. The white sheet will help you find them. I had a one foot magnetic tray in my lap.The apron rolled springs and parts to my lap, the magnetic tray caught the safety plunger and spring about 100 times. Maybe a 1000 times. I had real trouble with the safety plunger and spring, getting them in, and keeping them in as I pressed the hammer pin in. The plunger has a flat bottom and the safety hole was sharp edged. The plunger would hang up on the edge of the safety hole and go flying with the slightest movement. The spring tended to follow. It was very frustrating.
I got better as I identified punches that fit exactly and I found a plastic handled brush to jam the safety in place while I installed the hammer and hammer pin.
And of course, when you get the hammer installed,that is when you find out the trigger return spring fell out!!!
I also had the sear spring pin fall out
I learned to put a piece of duct tape over the ends.
