Ernie, I, and I?m sure several other specialty pistol shooters (maybe not on this site) use rifle scopes on our pistols. You just back off the scope and center the the field of view in the middle of the ocular lens.
I have photos of the sight picture. But, it?s a pain to load them in threads on this site.
Ernie wrote an article on how to do it. Maybe he can attach a link here.
