It's his pistol, and I'd like to learn to use iron sights first. I was surprised at how shaky I was (35 degrees outside), and know that if I was "tested" I'd be even shakier. But then again, we could install one for the initial learning curve and take it out later. Good advice. Thanks.

That Mossberg could tear a hole in an uninvited guest no matter how shaky I am and with no aim. But I do recommend switching a pistol grip for a combo.
