Believe me if I had more ready cash it would have a gasser on it but all I have right now is the 180 that has pulled the Sig Extre and the H( 73" Snap232 but I had to add so much weight ti the Snap232 that it must have came in as heavy or heavier that the WM Extra. I am probably worried about nothing because I don't really recall needing that much more power and if the 160 pulled it ok then the 180 shouls be about the same.
