We have dissected the P-10-C and have made some observations on the internals. Peering inside the "lock work" reveals a very simple, but unique CZ approach to the striker gun. Disassembly is quite simple, the only "trick" being a small spring loaded plunger block under the slide release bar.
Of interest is the fact there is no sear or separate striker release. The striker release is integral with the trigger bar and uses a simple kidney (like the 75 series lower barrel lug) to cam up and down. The striker release is governed by a simple "disconnector" that is pictured and identified further down. The striker release subsequently mates with the striker/firing pin. The camming down of the trigger bar/striker release is what allows the striker/firing pin to travel to the primer for ignition. Very simple.
This is the "disconnector" (think of the upper humps on the 75 series trigger bar or the disconnector used in the 1911). This ensures the trigger bar/striker release operates only when the slide is fully in battery and prevents ignition unless the pistol is fully in battery. Notice the rounded portion sticking out on the right, which makes contact with the slide rail and is constantly rubbing within the slide rail itself.
This is the forward frame support and slide lock unit. Notice the little semi-square hole in the bottom. This is where the tiny slide lock block pivots within the insert (more on this latter). We feel this small block should have been made from steel and in our sample P-10-C this little block already shows some minor dinging.
This is a snapshot of the other main parts in the P-10-C. Of note is virtually everything is MIM (metal injection molded), and cast from either metal or plastic. Of note on our sample CZ is the trigger measurements: 5 mm of pre-travel, 2 mm of creep before the break, about 3 mm's of over-travel, and we consistently measure a 6 lb. 6 oz. trigger pull. In our shop we collectively agree the trigger can be uncomfortable. The pivoting safety blade does not go flush with the trigger face and creates a sharp edge that could be annoying.
This part we like the least. This is the small block that holds the spring loaded take-down lever in position. It also has a coil spring under it to maintain tension. We are already seeing damage to this from just taking it out. Plan on seeing this replaced with a better part.
This is the striker assembly. Of note is the fact CZ decided to utilize an internal firing pin/striker block, combined with the Glock style pivot in the trigger. The striker block is contained in the plastic sleeve the striker rides in. So this means there are 2 automatic safeties. The very tip of the striker appears to have been contoured by hand (and on our sample was not concentric), which is surprising. The striker retaining cups are plastic, which is fine.
We like it, but we would like to see the 5 mm of pre-travel, 2 mm of creep, 3 mm of over-travel, and the rather stiff 6 lb. 6 oz. pull straightened out. It is also nearly impossible to close the slide using the slide release. We feel these can all be addressed.
