Lot arrived in good time easy to install improved trigger and hammer a lot
I installed this spring kit on my mod 360 and could not believe how much the performance changed. It truly felt new and improved ! So I couldn't wait to buy a second kit to tune my other j frame. I highly recommend!!!!!
I installed the kit easily after watching the TK Custom video on YouTube which brought back old memories from 60 years ago. Now the 642 stages easily to a distinct single action release similar to my Kahr CM 40. McGivern, Keith, Cooper, Weaver, Gaylord would all appreciate these improvements.
