Was this test based on a standard M&P 40 as opposed M&P Pro 40. Could the same been done with a M&P Pro 40 using a 9 mm barrel for a M&P Pro 9 and 9mm magazine?
Joined today, don't own a S&W but interested in seeing what the community thinks about certain models. Active shooter, interested in AR platforms, just retired from the Army Reserve after 30 years with one deployment under my belt.
