FWIW; SIG Sauer operates a training center in metro Orlando FL. They may be open to the general public or new LE cadets. The Orlando PD uses the P226R in 9x19mm. SWAT & detectives(homicide, DED/narcotics, etc) use the P226R or P229R in .40 or .357sig.
The Osceola County Sheriff's Office uses the Gen 04 Glock 17 9x19mm & are authorized to use the Glock 26 9mm, 19, 22/23 .40S&W. The Orange County Sheriff's Office has issued the Glock 21 series since 2002 with good results. Sworn deputies & detectives also tote Bushmaster M4s in 5.56mm, Remington 870 pump shotguns, HK UMP .45acp SMGs(select fire) & X26 Tasers(EDWs).
Orange County also hosts the big SWAT round-up every year. A event for sworn LE tactical units & spec ops. See
www.OCSO.com or contact the NTOA; National Tactical Officers Assoc.
To my limited knowledge, no sworn LE SRT or SWAT members in central FL carry 1911a1 .45acp sidearms with or w/o white lights.
Most sworn officers or agents I've seen use Glocks or SIG Sauers. The Daytona Beach FL SWAT unit is all volunteer so those officers may use 1911a1 models depending on the PD's regulations or policy.
I've used a 1911a1 .45acp on duty for 12mo as a lower enlisted MP in the US Army. I'd carry it if required but I wouldn't pick it as a SWAT or SRT sidearm. Many working cops & spec ops use SAO or SRT(short reset trigger) pistols but Id want a P220R DAK(Double Action Kessleman) or a HK45 LEM(law enforcement modification). The Viridian green laser/white light is a good add-on.
