Made to replace the OEM spring with a like product. 

Made from Stainless, no plating to flake off. 

Designed for consistent throws and long life. 

This product is still in early stages and we appreciate feedback. 

We have noticed after some time installed, that upon removal it opens slightly. We have not seen a drop in performance. It can be lightly pushed together. 

We recommend slipping one side, then the other. Do not spread to install. 

Since this product is so new, we are eager to learn the longevity of these, Preliminary testing shows several thousand rounds, without failures, however the CZ 457 vary greatly, and extraction problems that are present in one action can occasionally be challenging to replicate in another, so we appreciate your feedback with these.
