I don't own a DW, but have 8 different 1911's. they are 9mm, 38 Super, 9x23, 45 and 10mm. To say I enjoy my 1911's would be an understatement.
That being said, one of my favorite guns is the CZ Accu-Shadow. The first thing I did was convert to SAO. It is a pleasure to shoot. As accurate as any 1911 I own. Trigger is exceptional.
Comparing a CZ to a 1911 is like comparing apples to oranges, as they are completely different other than going bang everytime.
That being said, if you have never owned a 1911, it wouldn't hurt to add one to the stable.
