I was wondering if any current or former SWAT could speak about their ammo choices here and why. Many use the 1911 and not in 9mm. Why the lean in many cases towards .45? I'm my state, the state police SWAT pistols are .45 (with the exception of the 9mm Glock 18).
This isn't meant to encourage a caliber war. SEALs chose the Sig in 9mm for a reason. I would just like to hear about any anecdotal or test driven reasons for the calibers used. I often ask myself why an agency will default with 9mm or .40 but then their SWAT universally uses another caliber. Thanks.
