Simple installation. My CZ 452 limited edition went from 3.5 pounds to 1.5. I was skeptical but it actually works.

I was able to perform the trigger upgrade thanks to the great video produced by M Carbo. Instructions were clear, complete & much better than other half ass videos found on U tube. Cost of the part was very reasonable. Shipment was extremely fast & I even got a brake on shipping charges ! Couldn't ask for anything more. I'm very happy with the way the trigger upgrade turned out.

Fast shipping appreciated. Trigger spring install video accurate and helpful. Spring reduced pull weight as advertised. Note: This spring does not correct the creep that happens randomly with my CZ 455 trigger. Overall I am still pleased with the upgrade.

Great Product, fast shipping!

I found it very easy to install and it worked fine. Previously I had adjusted the trigger to as light as it would go which was 2 1/2 pounds; not bad, but I wanted it lighter. The new spring brought it down to 1 1/2 pounds and now it feels real good. I did think that $12 was a little high for the spring, but it works as advertised.
