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.
