Overall Customer Rating of 81 Reviews:

Didn’t feel any different

Exactly as the title says. Didn’t feel any better than the OEM springs

Great improvement much better feel.

Well worth it.

I bought this spring kit along with the mcarbo after-market trigger for My PC 9 M-lock. It brought my trigger pull down to 3 lbs! The semi-flat face trigger ensures my trigger finger always has proper placement, for better leverage, and consistency. Well worth the time it took to install it, and the money spent. I also purchased the mcarbo heavy duty recoil spring, compensator, and stock pad. See my other reviews for write ups on these accessories.

This Trigger Spring Kit was easy to install, video instructions were easy to follow. Spring kit delivered on the 1.5 lb trigger pull. Love the PC9 and the upgrade.
