M-41 Fail to Fire

Kp321 · Jul 21, 2020

I’m working on a M-41, mid-70’s manufacture, that fails to fire most of the time. I am in the middle of troubleshooting and thought I’d solicit some advice. Apparently the hammer is dropping to half cock rather than all the way when fully assembled. With the slide off, the hammer drops properly. First thing I did was get the overtravel screw out of the way so that’s not an issue. I am getting ready to swap the slide with one off a known reliable shooter.
Any other advice?

I thought immediately of the possibility of damage or wear and tear on the trigger bar, or that the slide might not be going into battery fully. Have you measure the trigger pull? Does it seem within specifications?

Thanks for the responses. The problem was a combination of trigger bar and slide. The bolt face had a burr plus the disconnector was not matched to the notch in the slide. I suspect some indescriminite parts changing in the past.
