What type of handguns are carried by the Florida State Police?

The Police use Standard Baretta M9 Sidears

Sorry, that is not correct. SOME police may use Beretta M9s, but all police do not. In the United States, each department sets its own requirements for what officers carry. In the city where I live, officers carry Sig 229s. In the county, officers carry Sig 226s. In another city near me, officers carry Glocks. In yet another city, officers carry H&Ks. All of those I mentioned, carry .40 S&W caliber. All that said, however, Glock is the most common. There are something like 4 millions police officers world wide that carry Glocks.
