Rocketflip. www.underwoodammo.com A little 1911 slug-launching to celebrate the 101st Anniversary of the 1911. :-) Thanks to Underwood Ammo for supporting the channel with the number 1 "staple of Compound life." Seems to be really quality ammunition, made with high quality components. I can't seem to get into my head that the Commander side 1911 has a 4.25-inch barrel. I keep saying 4.5-inch barrel in videos. :-) Well, I guess I just have too many decades of experience with the standard 5" Government Model. Being a senile old man could be a contributing factor, as well, I suppose.
