Work great in my Stock Master
Replaced the eom one with the 15.5lb one. Feels about the same as the oem spring. Going to try the 14lb later.

Working Quality!
Extremely well made!

The stacking is done
Picked up the 15.5 lb spring for a new Stock 1 SF. The stacking near the end of the double action pull is gone, and the trigger pull is smooth all the way through.

Hammer Springs
Ordered a 15.5lb and 16.5lb and did not receive the right springs the first time. I sent an email and got a response the same day and they corrected it at no charge, that's great customer service if you ask me.

Hammer spring
The new heavier hammer spring that Joe/Joanna recommended, worked great to prevent light primer strikes, which were caused but todays harder primers.
