After having bought trigger spring kits for my Ruger Americans I purchased kits for my CZ 452 and 455. They are just as advertised and reduced pull weight and creep. Thanks for a product well made in USA! Dan.

I replaced the stock trigger spring which had a 2.5 lb. pull with the M-Carbo spring which has a 1 lb. 3 oz. pull. The trigger spring is great!

Works perfectly. Just dropped it in, along with the extended mag release, and they worked great. Reduced my trigger pull to about half of what it was. Both parts are quality parts and I highly recommend them.
