I'll take big 'n slow over light 'n fast every time. But that's just me!
The same reason a lot of police departments in my area are getting away from the 9mm and going to the .45ACP
That's right. Seems to be happening everywhere. They've at the very least moved up to the .40 S&W over the 9mm. Bigger is better as long as you are capable of shooting it.
