I've never had any trouble with the Overland Stage double-barrel but it put a nasty bruise on both my husband and my daughter's boyfriend. They both braced it against their shoulders like you normally do. I hold the butt under my arm, against my side, and hold the barrels down with my left hand, from the top side. I know that would make some instructors cringe but it works for me. I don't get bruised and I can keep it under control. My husband has a Remington 1100 with gas recoil and it's a Cadillac. My 12-GA is a cannon. BTW, the term "knock you off your feet" was just a figure of speech. I have seen my Overland Stage make grown men take a couple of steps backwards though. :-)
Very glad you're up to speed on the "using" of this stuff. I had to assume otherwise, just to be sure, but I sure don't want to sound like an authority giving a lecture.
Many people around the world read these threads, and I desired to cover the waterfront for them. The typos were thrown in just for fun.
Trust me.
