Hi Power issue- hammer goes to half cock sometimes

[kaltesherz]

I have a FN made Mk III that had some work done on it by a very well known Hi Power gunsmith. Every now and then, when I release the slide sometimes the hammer falls to the half-cock position. What could be the issue?

[DanjojoUSMC]

Too much polishing of hammer/sear engagement, hardness of those parts or angles are off, depth of notch is too shallow.

I had a MK III HP that would do that if I released the slide on an empty chamber.

It did it on a live round at the range the other day, and it wasn't the first time. Should I send it back to the 'smith?

Yes. And quick.

[kaltesherz]

Thanks, will do.

depending on how recently the work was done, i'd consider sending to another smith. this isnt supposed to happen on a new trigger job. you might also want to consider using a c&s matched tool steel sear/hammer.

This. It could start doubling (or worse) which could put subsequent rounds over the berm. I've had that happen with a 1911 and it's no fun.

I think this would actually be impossible on a MkIII with an FP block. After the slide cycles, you'd need to reset the trigger before the FP block can be moved.

You may be right. But technically, you need to reset the trigger on a 1911 before it can fire, too.
