CZ-52 Firing Pins

The Czech CZ-52 is well-designed and represents the relatively high quality of Czech metalworking and construction. The design and the powerful cartridge — achieving 1450-1900 f.p.s. with an 85-grain bullet — makes it accurate and effective at 100 yards and beyond. The guns themselves and surplus ammunition are readily available and inexpensive.

Unfortunately, the original design had two drawbacks related to the firing pin design.

CZ-52 original firing pins, two with broken and missing noses.

First, the original military design calls for a very heavy military-style trigger pull. This lowers accuracy and makes the pistol less fun at the target range.

Second, the original CZ-52 pistol firing pins frequently break.

Here you see three firing pins made to the original CZ-52 design. The replacement one at top is still serviceable, but the other two have broken and missing noses.

The original pins were actually cast, an unusual (and not very reliable!) method for manufacturing firing pins.

On top of that, they were made of relatively weak steel.

Dry-firing quickly work-hardens the thin noses of the original CZ-52 firing pins, and the nose can break off after just a few rounds of dry firing.

As you can see here, the pin tends to break right above the rounded fillet at the flat shoulder.

This is because that flat shoulder slams into the end of the roughly cylindrical firing pin cavity. The neck of the nose impacts the rim of the firing pin opening, as if to extrude the cast steel through the opening.

This quickly work-hardens the cast steel and makes it brittle, guaranteeing that the nose of the pin will break off after just a few rounds of dry-firing.

The original design could tolerate the compression of the nose when it impacts the primer while firing a live round, but dry-firing work-hardens and breaks the neck of the nose.

Harrington Products has come up with a series of products which will help your CZ-52 to achieve its full potential. We have re-engineered the firing pin design for the CZ-52, and we precision machine replacement pins from tool steel that we then harden. This virtually eliminates breakage.

Our design does not allow the nose of the firing pin to contact anything but the primer during firing. When dry-firing, the forward motion of the pin is stopped by a an added firing pin return spring. The firing pin nose is therefore immune to damage from dry-firing. We do recommend, however, that if you intend to dry fire the pistol for thousands of rounds that you remove the firing pin to prevent peening the rear of the pin.

As an additional benefit, the design eliminates the heavy military trigger pull of the CZ-52 pistol. This "drop-in trigger job" results in a crisp trigger in the neighborhood of 3.5-4.0 pounds. If you would like to see what trigger pull results from our drop-in trigger enhancement of the CZ-52, simply remove the slide from your pistol and dry fire the lower receiver only. For the maximum benefit from our firing pin / trigger conversion, we recommend you also install a heavy Wolff recoil spring, 16.5 pound or heavier, available at http://www.gunsprings.com/
