I’ve seen a couple police officers carrying M&p’s, nowhere near as many as I’ve seen carrying glocks over the years. Big surprise right? Not. While in a cab in Indiana we smoked a deer on 24 and when the Wabash police came to dispatch the dear low and behold they had M&p 40’s. While in Cincinnati a few years back I seen some cops carrying M&p’s. Heck even Ottawa Hills police in Lucas county were carrying xd’s over a decade ago (don’t know what they carry now). To this day that is the only police department I’ve seen carry xd’s and I’ve gone all over the U.S., but I’m sure some small department somewhere else issues xd’s. Just because you don’t see it doesn’t mean it doesn’t exist. I don’t see any men wearing fanny packs anymore, but I know they’re still out there somewhere (cough cough yankee marshal, nutnfancy cough cough). Glock took over U.S. law enforcement duty rigs for 30 years, it’s going to take time to end that reign. I’ve yet to see a Cz or Fn in a leo holster. M&p’s are scattered thin, but it’s not like looking for Waldo. If you go enough places and see enough police departments you’ll see plenty I'm sure
