Thank you so much, jmstr! That is a MCUH safer feeling way to go about this.
I just tried it and the pencil only moved about two or three inches, I did two more times just to be sure. Then just to make sure I put a mag in... triple checking the chamber to make sure it wasn't loaded and tested it. The pencil moved the same distance
I think I'm going to email Sig about it when I get home.
I am from that Lancaster by the way.
