Marvel sear jig can be easily fixed
Yes, the sear pin pulls out of the sear attatchment, I found this is easily fixed if you are familiar with staking a hammer strut pin. I staked the threaded pin after using it a few times and the pin started to pull through. Clean the end of the pin and the inside of the hole where the pin is attatched, I put a small amount of 2 part metal epoxy on the end of the pin and staked it on the back side using a standard punch, cleaned up the raised portions of the staked pin, ground it smooth and flat so it wont scratch the jig body. 5 trigger jobs later and the pin has not moved yet. I found the trick is to NOT torque the nut so that the pin has a chance to pull through, I believe it does not take that much to secure the sear to the attatchment.
