Hi! I just recently discovered that some Sigs that are DAO can be converted to DA/SA with a decocker. My first Sig was a full sized P220 45acp with a decocker and I loved it. Fast forward decades and I find myself with a P220 SAS DAO that I would LOVE to convert to DA/SA but here’s the kicker, my P220 doesn’t have a decocker bearing hole in the frame! Does anyone know if this can still be converted and by whom? Obviously the frame will need drilled out.
I appreciate any help!

I seem to remember Robert Burke TheSigArmorer doing some CDNN P220C years ago.

Might be worth contacting him and finding out if he is still doing them and if its cost effective to mess with.

Thank you so much, and I will contact him.

Well, strike one. Sig Sauer custom shop said that they are not set up to convert my frame to DA/SA so they are out. The Sig Armorer did get back to me and they wanted to see some photos of my frame. So far I haven’t heard back from them. Hopefully they can do it.!

Strike two. Robert Burke (the Sig Armorer) says:
No provision for the decocker. You’ll have to stick with DAO.
Frustrating. I was very excited at the possibility!

Well thats all i have to recommend. Looks like its DAO or selling it.

Thank you though!!!
