I had the DAO compact 3956 (I think that was the number). It blew. Everything that I didn't like about it had everything to do with the trigger. The rest of the gun was fine, but the trigger pull was with worst. The idea is to basically give you a revolver, and that's fine, but the trigger pull itself is diefferent than a revolver and I find a wheel-gun DA trigger pull to be far easier than the DAO Smith. The DAO Smith pull is lighter and shorter than the DA pull on a DA/SA SW but I found accuracy to suffer enough that I just didn't like it. I eventually figured if I had to practice enough to get decent with the DAO pull, I'd have practiced enough to be good with the DA/SA transition and have better accuracy.
The steel frame full size SW is a pretty good auto at usually a pretty good price. With the heavier frame, recoil was non-existant and mags are dirt cheap. Being stainless is a bonus in any wet climate. The gun is fine, but I would say you need to thouroughly try out a DAO before you sink your money into one. Remember the DA pull on a DAO is different than on a DA/SA so you can't compare unless you try out a DAO. Used DAO's usually cost less on the market than DA/SA, but it also means they are pretty hard to resell if you decide to get rid of it. If it's your type of gun, then it's great news for you, but make sure you try one out first.
