I've had a couple HP pistols but this is my first carbine. Seems to shoot pretty good, I'm having some issues with it feeding my hand loads, too long I think. Rounds are getting jammed nose up and the nose of the next round is getting jammed down. My real issue is how uncomfortable the grip is for me. I've got big hands with short fingers. I think I'm out of luck on reaching the mag release with my firing hand but my hand gets fatigued when firing. Is there enough meat in that grip to slim it down? Specifically the raised portion about where the mag release is? Seems awful thick for that little single stack magazine but is it solid? I don't want to start sanding it down and find out it's hollow.
