But yes, he's right. Actually though, I could have clarified that when I do purchase the Dan Wesson 10mm , I intend to sell my .45 -- both of which are "large caliber man stopping" guns, so I wouldn't really have two anymore anyway.
Don't sell it off immediately. Cheap .45 ammo is a lot easier to find than cheap 10MM. 10MM is a great round though. High performance. You will need to change out the recoil spring every 2 or 3 thousand rounds, which you really don't have to do with a .45. Also there is a 10MM forum http://www.10mmtalk.com/
If you get the 2.5" barrel .500, let me come watch you fire the first round.

I have shot (but do NOT own) the four inch. Accurate but way, way more than a handful.
Have you ever been to the big gun show in Tulsa?
BTW, personal experience on clothes - when I left active duty, I would come to a dead stop in front of the closet in the mornings trying to figure out what to wear. Previous to that, it was SO simple.
