I bought the K6 for the wife. The smoothness and relative ease of the trigger pull was what she needed. Of late, as her arthritis progresses she has had difficulty squeezing the trigger. I've done a little business with TK before, so naturally, I decided to give them the first try on making this trigger better.
Ordered the parts and received them PDQ. Set aside an afternoon for installation.
Took less than a half hour. That dadgummed bolt spring can be a bear.
Trigger pull gauge showed improvement from 10 lbs 7 oz, to 8 lbs 13 oz.
Took it to the range today for function and safety check. Primer ignition was positive on every single brand of ammunition tried. Geco, PMC, PPU, Norma, Aquilla, Speer Lawman, Blazer Brass, Federal and Remington.
I could find no fault in the kit. Buy and use with confidence.
I'm considering a S&W 640. Should I get one, the similar kit will be purchased.
