A couple of weeks ago I took it out on an armadillo patrol at deer camp. Laid a few 'dillos in the dust with it. Dispatches them much much better than a 22.
It was really supposed to be a backup gun, but I find that I'm grabbing it pretty often as my primary when I'm in a hurry or just don't feel like carrying a 45. It's not the gun so much as the mags which are so much thinner and lighter.
Oh, and while at deer camp, I did a water jug test. (I previously did 9mm and 45 ACP water jug tests) It actually had a little more penetration than the 9mm and slightly less than the 45 (all using XTPs). Went through three jugs, hit the fourth, then bounced back into the third. The 9mm stopped inside the third jug. The 45 stopped inside the fourth jug.
