Works for me.Hitting your target is the #1 goal, doing enough damage to stop the threat is #2, and having a firearm that is ultra reliable is #3. No matter the caliber, with the right ammo designed to do the job at hand, whether its a gold dot, hydrashock, +p or -p, or whatever else, as long as it does its job effectively, who cares what caliber it is. Their are instances where 44 magnum to the cranium wasn't enough, and I am sure their are instances where a 22lr did fine. I say they should decide what tool they need to accomplish the task. We who carry do the same thing for our own personal reasons. I would not want to be hit with any of them, under any circumstance. Just my honest opinion.
For decades, the standard police issue sidearm in Sweden was the Walther PP in 7.65 X 17mm (.32 ACP). That was the same round that was the standard police round in many European countries. It wasn't until drug runners started showing up with bigger calibers that those police agencies "upgraded" to the 9mm.The metrosexuals attending the FBI academy today can't handle anything bigger than the 9mm. I can see the FBI going to the .380 AP or .25 AP in the future.
