A pair of "Firing pin Retainer pins" (roll pins in the slide) for the CZ PCR (75D).
My dry-firing wasn't very much (maybe six DA pulls every few days), but No Snap Cap or O-ring had been used., and the dry-firing had produced accumulated stress on the factory pin.
There was a tiny oval-shaped. tear in it.
The Harder, highly-recommend pins (by gun owners) from Cajun Gun Works are hollow, and CZ recommends using only hollow pins. It took about 3 min. of tapping with hammer, while getting the pin aligned, just started into the hole, then was easy.
What isn't clear after a few hours of much reading is
Whether Only shooting ammo (?)
, ie a thousand rds., can cause similar tears in the original CZ factory pin ...?
These stresses (holes, gashes) can result in an inop / jammed firing pin.
Note: this is Not criticism of CZ.
They produce excellent guns, and a few dollars plus a few minutes replacing the OEM with a newer Harder pin is all the 75 series needs.
The earlier Czech & Slovakian police and Army probably expected to replace the pins every 500 or so rounds. It’s very easy….
