Highly Recomend(20/12/2009)
I used this spring along with a 14# rebound spring, dropped DA trigger pull from 10# down to 7.25#. Made a big difference in the feel of the trigger. An easy trigger job for the do it yourselfer. You will need the special tool for removing the rebound spring, makes it alot easier.
Excellent Replacement Mainspring(03/04/2012)
I have used this mainspring for over 20years in competition, duty and carry guns I build without a failure to fire... Excellent, It always works and have never had one break.
