Upgrade your CZ457 firing control group for consistent and reliable ignition. This Chrome-Silica spring is made in Canada and is a direct OEM replacement. Combined with our stainless steel / brass thrust plate, this kit will no longer allow the firing pin spring to wear in and bind into the factory plastic bolt shroud allowing for very consistent firing pin control and improved lock time.
