After a night of tossing and turning - Ruger vs Walther, I finally hit
the button on the Walther.

Luddite has said he likes his Walther, and the reviews seem pretty
positive. With the Colt/Walther combination, it can't be too bad a
gun. And I sure like the looks of it. Also, it's very much like the
Kimber .45, but a lot cheaper to shoot.

So, Tim and Wayne - thanks for the help/advice. I'd been thinking of
getting a rimfire conversion kit for the Kimber, but, as Tim said, for
the cost of the kit (over $300), I could just buy another pistol.
