Yeah, that's a neat little carbine. I saw a couple at the local gun shops. My friend got a Beretta Cx4 Storm chambered in .45ACP recently, and it's a pleasure to shoot. I'd probably go for one of those considering I don't need to conceal my weapon. Still, you've got a nice little "work-safe" package there.
5.56, since you're such a big GLOCK fan, I've been meaning to ask what you think about the GLOCK 20, my personal favorite. Lots of people say it's not a practical carry weapon due to the sheer power and penetration it offers, but these are plusses in my book.
Up where I live, I'm a lot more likely to use it on a black bear, mountain lion, or deer than a human aggressor. I've read reports that due to the low barrel axis of the GLOCK the recoil is quite manageable. Can you confirm this?
