So if not USPSA open, what competition might the M&P40L pro-series C.O.R.E. excel in?
Without the dot, you could be competitive in USPSA Limited, Limited 10
and Production (assuming it's on the Production approved gun list).
I made B in USPSA Open division with a G35, with a red dot on a Carver
mount and a cheapy ported barrel. It was fun, but I got my butt handed
to me by the real open gun shooters on the longer field courses.
