MKIII steel frame Hunter Trigger Problem

Post by recumbent » Sun Jan 27, 2008 6:29 pm

MKIII Hunter steel frame, mag safety removed Marvel trigger every thing else stock.

the above modifications were done a month ago and everything was fine until today.

Dry fire the pistol without the Mag in it about a 3 lb trigger pull.

Put a mag in it and it goes to over 10 lbs feels like the safety is on but it will fire.

It has never done this B4.

What should I look for?

Thanks,

Check to see that the mag body is not adding drag onto the disconnector lever. That lever also acts as a trigger bar and any drag would greatly increase the trigger pull.

Also, what kind of set-up for the hammer bushing are you using? The disconnector squared hole could be hanging up on the bushing when the mag is installed, due to the mag knocking the lever slightly out of alignment.

Hope this helps.

I'll check it tomorrow night.

The hammer is a MKII hammer and MKII bushing.

The hammer and bushing configuration should be good. Doubtful that there's any disconnector interference with those parts.

I fixed it.
I had replaced the curved part of the Marvel trigger with a straight trigger I had made. I had a MKII 4 inch upper on the frame and everything was fine.
When I put the MKIII back on the MKIII lower is when I had this problem.

Changed back to the stock Marvel curved trigger and it's OK now. I cannot tell where it was hitting and don't understand why it would work with a MKII upper and not with a MKIII upper.
