Cooper 38 issue
Gentleman,
I have a reoccurring issue with the firing pin retaining screw backing out and causing a misfire. Is there a procedure to hold the firing pin while snugging the retaining screw? I am hesitant to use a thread locking compound in case the firing pin should break/or need to be replaced. Thanks, Rider |

Years ago......I used some clear fingernail polish.
Worked pretty well. Kevin |

There are multiple grades of thread locking compounds. I know with Loctite brand red is considered permanent and blue is serviceable. I think there's a puple for fine threads too. Just don't use red as it takes quite a bit of heat to soften.

Does anyone have a method to hold the firing pin while snugging the retaining screw?

To hold the firing pin in the correct position, I use my borescope to look in the hole, but any good magnifying lens should work. After you get the holes lined up, just install the cone point setscrew and tighten it a little. Next install the second setscrew with a little blue locktite to bind the first one in place. Let it sit for a little while so the locktite has time to set up and you should be good to go. Forgot to say that after you disassemble, make sure to wash all the lubricant off all the pieces so that the locktite will bond to the steel and don't re-lube untill it has time to set.

SmokingJoe,
I don't know how I missed the set screw in the cocking piece. Pretty obvious! Thanks, Rider Last edited by rider; 04-03-2020 at 02:41 AM. Reason: spelling |
