If you can shoot a handgun accurtley , I would pick the 357 sig over a 9 anytime ( reason u see more LE agencys going to the 9mm is ammo cost plus some men& women have problems quailfy with hot caliber round main reason GA LE statewide has changed over to the 9mm
That ain’t exactly true. Look at the results of the FBI testing with several loads that caused them to switch from .40S&W back to 9mm.
I don’t doubt that some agencies are switching due to cost of ammo, or ease of shooting, but not all are doing it for those reasons, or at least not for those reasons alone.
