It's not just Kimber. I'm an STI fan and they only come with one mag. I'm on my 12th STI so I'm used to it, but it just seems like they could do better or at least give you the option of adding additional mags to come with the gun. Whether buying a 1911 carry gun for a $1000 or a 2011 competition pistol for $2000-$3000, you still just get one mag.
