CZ-52 Firing Pin Slide bore damage

mrweeby
Hi, I need help finding someone or a tool that will fix this problem:
The bore in the slide where the firing pin goes is damaged. The damage is in the area where it "bottlenecks" down to the small hole where the pin strikes the ammo primer. I bought a damaged gun from gunbroker a while back. It had a broken firing pin glued in place. Also light damage on the pin retainer/plunger. I replaced both parts. I cleaned out all the "glue" substance. The new pin will go in about 97% to 98%. The last small amount of travel where the pin protrudes to strike the primer is where it gets stuck. It will not retract to a safe position. I need to find someone that works on these guns, or I need a reamer tool to clean up the pin bore in the slide. HELP!!

    Firing pins commonly break on this pistol.
    There are aftermarket firing pins that are more durable.
    Apparently one broke in yours raising burrs in the firing pin channel.
    Find the correct size number drills for the several bores and use them in a tap wrench to cut off the burrs.
    Alternatively, determine the sizes using number drills, order reamers from MSC and use them in a tap wrench.

    Thanks for the input. A few other questions/thoughts. Who is MSC? Address? web site? Also if I can find reamers that will fit the slide firing pin bore, I will also have to be looking at the cutting angle of the reamer, making sure it is the same angle as the shoulder angle on the firing pin. I think it just needs to be lightly cleaned up. Does MSC have different length and degree angled reamers? It would have to be long enough to stick out from the rear of the slide so I can get some sort of handle on it to turn it. Any other thoughts will be appreciated. Thanks.

    MSC Industrial Supply Co. is on the web. Google them.
    They supply ones and twos of machine tools
    I really don't think you will need to clean up the front of the big bore. The firing pin will knock it straight. You could always grind the tip of a drill to match the firing pin cutting angle. Your sizes will most likely be metric.
    Gage the holes with number drills and use the nearest metric size.
    They also have long drills

    Ah yes MSC Industrial. I know who they are. Thanks for the input. Anyone else care to share about experiences with the CZ-52? I now have three of them, first one shoots great and looks ok, second one is the crap I got from a crooked dealer on gunbroker. Third one I got two weeks ago, Looks near mint but haven't got to shoot yet. Local dealer says it's fine and will take back if it isn't.

    My first one shoots very well, and is pretty accurate. As I said the second one I got is the one I am trying to get fixed. I'm planning on shooting the newest one (3rd one) asap. Would like to find some factory mags at a fair non inflated price. Ammo is the cheapest centerfire on the market now.

    Shh, that too will dry up.
    If drills or reamers aren't long enough, a machine shop can braze on an extension.
