Made to replace the OEM spring with a stronger product.
Made from black spring steel, no plating to flake off. Keep lightly oiled.
Designed for stronger, more consistent throws and longer life.
Do not over spread upon installation.
We recommend slipping one side, then the other. Do not spread to install.
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.
