We issue the M&P, most have the original but now we are issuing the 2.0. I shoot my personal 2.0 5” when teaching recruits (sometimes) and it’s an awesome gun, but personally for carry and field use, I bounce back and forth primarily between Berettas and 1911s. Duty ammo in 9mm and .45 respectively is Federal HST 147gr and 230gr with the option of Winchester Ranger-T 147gr or 230gr... all standard pressure.
Issued holster is the Safariland 6280LASD, which is what I use for M&P and Berettas. For 1911s it’s... tougher. We may be going to the 7TS series soon for issue but we’ll see.
