Nice kit
This is awesome, just do everything but the trigger first. Took it apart 3 times before I realized the trigger was adjusted for the original parts. Otherwise it was smooth and works great.

“Ultimate” Trigger MKlV 22/44
Installed this kit on both my Tactical and Light and the difference is immediate. Trigger pull is about 2.5 - 3 #s and very crisp. Recommend this if you are looking to upgrade . Plus the folks at TK are more than helpful or you have any questions or concerns.

Ultimate Trigger Kit for Ruger MKIV 22/45
Reasonably easy to install, just go along with the video and take your time. Very well made, the machnining is perfect. The factory trigger on the MKIV 22/45 is marginally acceptable at best. This kit changes all that. Beautiful trigger pull. Light, crisp and precise. I like the shield for the hammer and sear. Makes a big difference in keeping the internals of the pistol clean. The flat trigger and its adjustability enhances the trigger action even more. 100% recommend this if you're looking to drastically improve your trigger.
