That probably wont work because you need a DAO hammer and sear.
You might try to contact s&w and see if they will do a DAO conversion for you. I doubt it, but worth a try. If the 1st CS rep says no, be sure to call back again. You just might get a different answer from another rep. It happens.
Tarnhelm Supply was doing 3rd gen DAO conversions for some time. I would try them too. Good luck! Regards 18DAI
