I have a couple of issues withthe Kimbers 1.) The breakdown of the gun is dumb. It would be hard to fieldstrip if you loose the wire
This is only true if you buy a "Pro" or "Ultra", aka Commander or Officer sized. Most, if not all, full sized Kimbers have a standard barrel bushing and guide rod.
And for the OP, 10mm is a good bit more expensive than 45 and is harder to find. But it is a hoss. It beats the 45 by a sizable margin in terms of power, but if this is your first 1911 I would stick with 45.
My vote is the S&W.
