A Glock 22 with OEM sights and 180g HP Federal will hit a B-27 at least 10% of the time at 200 meters. BTDT. If you shot from the roll over prone position I suspect you could do a little better.
I purchased another G19 Blue Label today. I suspect the 9mm with decent 124g ammunition will shoot a bit better at 200 meters.
