So, Ive done the basic Google search and can't find out if Sig made a P229 SAO, that wasn't a Legion. I'm sure they have in the past - but I can't find a reference. Any help would be appreciated.
Pretty sure the did not.
The Legion is their high end line, and the SAO was designed to compete with and appeal to 1911 snobs.
I will say, it is the bee’s knees.
