I HAVE A GAMO SHADOW 1000. WITH NO SCOPE MOUNT STOP HOLE. I JUST PURCHASED A FULL LENGTH ONE PIECE SCOPE MOUNT MADE BY LEAPERS/ACCUSHOT. I HAD TO REMOVE THE STOP PIN CAUSE THERE IS NO HOLE FOR IT TO GO INTO. HAS ANYBODY RUN INTO THIS AND IS IT POSSIBLE THAT THIS SCOPE MOUNT WILL SUFFICE IN KEEPING THE SCOPE MOUNT FROM SLIPPING. THE SCOPE BY THE WAY IS A POWERLINE 3-9 X 32.
