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.

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.
