I have a DW Classic Commander Bobtail, a previous version of a V-Bob, and a 9mm ECO. I had some problems with the Bobtail when it was new, but the ECO has been fine after the first several mags. The Bobtail was my first 1911 pattern pistol and I found I prefer a normal 1911 grip profile that keeps the entire backstrap against the hand, which makes for better shooting. Of course, the reduced bobtail grip profile conceals better. Another shooting versus carrying tradeoff...
I am especially fond of the ECO, which carries and shoots very well. FYI, Wilson Combat makes 9 round 9mm magazines for Officer grip size pistols that are only slightly longer than 8 round mags.
