Colt just updated the delta with a beavertail, Novaks, and an extended thumb safety. I have always wanted a delta, but didn't want to send another gun off to get all that stuff done. Now it comes with everything from the factory.
I'm not sure if the lack of a ramped barrel is a problem. Underwoods sells a delta load that is a 180
1240 whereas the regular loading is a 180
1300. Not sure the extra 60fps is that big of a deal. I am sure the Dan Wesson is nice as well. If I wanted a double stack I would (and did) get a Glock.
