In addition to the pin hanging up in the raceway, it sounds like the trigger-sear connection may have the wrong angle or too little engagement and that the pin may be jarred free by the bolt slamming forward.
Try letting it slam forward on an empty shell several times to see if that may be happening. Also check engagement by pulling the trigger slowly and seeing if there is the same amount of creep before the sear releases.
If you find that it's an engagement problem, that can be easily and inexpensively cured by a decent gunsmith.
