Everything you need to put a sweeeeeet trigger in your MKIV or MKIV 22/45. 04/18/2020 Made my Mark IV Hunter fun to shoot! The OEM trigger broke between 3.5-4lbs with too much creep. After installing this kit, 1lb 8.3oz. PS dental floss is helpful for installing the sear, sear spacer, and sear spring. Highly recommend Rimfire Sports shipped my order quickly and will be a repeat customer for future needs. 12/17/2017 Just installed this in my MKIV Target model. It is a HUGE improvement over the original factory trigger. My Ruger now has a trigger that rivals the best High Standard triggers. This kit is worth every penny and then some.
