you need to get out a little more, M&Ps are yesterday Ruger P89'sI'm not saying Glock isn't a decent gun, but don't put faith in the best weapon to buy being the one the military or police departments adopt.
The manufacturer who can meet the basic standards at the lowest cost gets the bid. Period.
I know a few officers who have given up their issued Glocks to carry their personally owned M&P's.
