A while back I discovered this item that lent itself to the the loading of a 1187. I installed per instructions. Except.................I turned the U shaped spring 180 degrees and created an obstacle for the round coming from the magazine. Need to get to the range.
They really work. I have seen them in action. For a load one and fire (pretend the bolt is locked back)drop one in the chamber. While mounting the gun and your left hand moves toward the fore end, push up on the forks as your hand goes forward.
Or load two. Drop one in the chamber, push one in the tube. Instead of hitting that little chrome button,the act of loading a round will drop the bolt.
