Definitely recommended

Brownells USA Great with lighter loads 16/03/2015

This works great for reducing recoil if you load your own ammo and tune it down. I switch back and forth between this and a 13lb spring.

Definitely recommended

Brownells USA Great Spring 07/05/2012

Excellent spring that last forever and is very consistent. 13# is a great weight for 130 power factor 9mm's.
