“Despite the F.B.I. switching to the .40 S&W, there are still a number of law enforcement agencies that continue to issue the 10mm including the Albuquerque J.P.D. and the Anniston P.D. as well as in Canada, where the Alberta Sheriffs employ it in the Glock 20.
The Government of Denmark has issued the Glock 20 pistol chambered for the 10mm Auto cartridge to members of the Sirius Patrols in Greenland.The pistols were issued as a defense against polar bears which the patrols encounter.

I’ve almost purchased the Glock 20 a couple of times. I ended up not doing so because I can replicate the ballistics with 45 super balancing better diameter with worse sectional density.
I’ve considered the 460 Rowland because both the 10mm and 45 super are a little wimpy vs a big angry bear. I haven’t purchased the 460 Rowland kit yet because honestly, it’s also a little wimpy vs big angry bear.
