Didn't know that, 3 gun is still pretty new to me. But I have learned the unmagnified Eotech ain't the best and my HD M500 converted to 590 with a Surefire is too heavy.Also, since you live in New Mexico, you do realize you're right in the middle of two of the biggest 3 gun matches held in the country, right?
Rocky Mountain 3 Gun is held at the Whittington Center in Raton, NM, and Superstition Mountain is held near Phoenix, AZ. Both are great matches.
