You can not change a DAO into a SA/DA by changing the hammer only. This should be obvious to you by simply pulling back the boobed hammer. Does it stay cocked in the SA position?...No, it does not.
If you don't like the DAO model, trade it in on a SA/DA model.

This may or may not be true because the SA notch is on the hammer and the trigger of the DAO model WILL engage it if a SA/DA hammer is installed. I have converted a DAO SP-101 to SA/DA. The hammer COULD have dropped in and I would have been done. As it happened, I had to do some fitting of the pawl and the trigger plunger (I think I used new ones) in order to make it work smoothly and get it timed right.

The more difficult issue would be finding a hammer.

This is correct. Aside from fitting, it will work because the DA/SA hammer has a SA notch and the DAO trigger does not.

I'm sure you meant "hammer". It sounds like you've been through this, as well.

As I said before, just trade in the DAO and buy a DA/SA. Monkey with the DAO and you will probably void the warranty...and BTW if you have car trouble, don't take your car to a shade-tree mechanic.

Hammers can be found at e-gunparts.com (Numrich) and from some others places but it usually takes searching for several months (or it did me). I even found once at a gunshop in MA using Google.
