Thanks for the above replies.
Just to be clear, there are two separate issues, IMNSHO. One is obvious: I was VERY specific about what I wanted (as in; I asked them to remove the single action notch, in addition to the other work)... that's a customer service issue and should be dealt with on that level.
The related issue (and the reason for my post) is that part of the vociferous counter-argument for failing to follow my instructions (written on the work order) was the 'smith in question's opinion that just bobbing the hammer was indeed "DAO". I am personally of the same opinion as Sam1911 above; that is to say, no it is not.
Unrelated, of course, is the issue of whether or not I am either a court-savvy, highly trained life-long firearms enthusiast or just a gun magazine-worshiping mall ninja for wanting a fall-back carry snubbie to be DAO. Opinions can and may vary there.
Fact remains: I stated what I wanted, agreed to the price, and then got what I thought was a bogus counter to a legitimate beef when the work was only half-done.
It seems that opinions on true DAO are more varied than I had thought on this forum, which surprises me a bit.
At any rate, thanks again for the replies!
