I fondled one in the store the other day. They feel very solid and are yet not too heavy imo. They make a pure dao version too. I could tell a difference in the trigger pull between the coc-kable and the dao's trigger pull. You know how sometimes dao have a better trigger pull. My lgs actually had nine of them I fondled up four of the nine. Quality seemed consistant.
They are odd looking for sure, but from a functionality standpoint I like their design. Some good ideas have been slapped into the bugger. I am still not sure I need one yet, but I am working on convincing myself. I am curious how they will hold up with more roinds, how the finish will do with lots of carrying, etc. The flatness of the cylinder does not buy much imo since this is too big and heavy to pocket carry. Now if they cake out with a smaller aluminum framed verson for pocketing, even if only in 38 I might really need one. I am actually rooting for their success. I kinda like em for some reason.
P.S. think ruger as far as build feel and what not. They feel very solid, but unfortunately have less of a melt if you will, having more shar edges than say a smith and wesson revolver.
