I personally have the DAO P-990 in 9mm. I also have a G-17 and a G-26. Lately, I have been thinking that I would trade both of the Glocks for a standard DA/SA 99, also in 9mm. The DAO is fine on a social gun, IMO, but for target practice the SA trigger seems like a better option to have. BTW, I personally have no problem with the first shot DA subsequent SA transition. YMMV.
