Ha! Reminds me of my last couple of girl friends! I really am old enough to know better, but I still go for the trouble-makers!Just writing this down shows me that the XD is probably the smart move(kinda like deciding to marry the ugly girl who'll be a great wife) but the Kimber still appeals to my baser instincts (Hot girl, nothing but trouble, maybe unreliable, and will definatly cost more to keep running)
As for the gun, well that is usually a different story. But....
You already have decent guns at your disposal. I say go for the trouble-maker and enjoy the ride!
