HPIN Hammer Pin
See “Description” for important installation information.
These are super hard, heat treated to RC60, and are a friction fit in Cajun Gun Works hammers, so no staking or peening is required. Requires 2 for DA/SA pistols; only 1 is needed for single-action only pistols. Fits virtually all CZ’s that use a CGW performance hammer.
One end of the HPIN has a slight bevel to ensure it starts into the hammer easily. This bevel also ensures the pin starts straight, eliminating any misalignment.
NOTE: For factory CZ hammers including CGW part numbers 10035, 10035 D/C, and 10040 CZ Competition hammers and hammer kit, a different hammer pin is needed, see our part number 75009.
See “Description” for Tech Tips and important install information.
TECH TIP: The only issue we encounter from customers is they can’t get the pin(s) to go fully into the hammer. The reason is simple: if you are laying the hammer on a plastic bench block, or a soft piece of wood, and using a pin punch, you will never get the pins in.
The solution is to use a steel bench block, or similar very solid base to set the hammer on, then use our starter punch (part number SP) or similar/suitable strong shouldered type punch, and the pins will go in every time. DO NOT use a vise to install the pins in the hammer, we will not warranty the hammer if you damage it.
Highly recommended as a replacement for the soft CZ factory pins. Our pins are heat treated to RC60 (tool steel grade) which contributes to a smoother action. Proudly “Made in the USA” from premium high carbon steel.
