 I am pretty stoked that I found her, brand new in 45 Colt.

HEY, you found one!  Does it match your other Omni?

No, as you can tell was built on a sheriff frame, which means no slot for the ejector housing, but I still like it. I will keep on the lookout for another Omni with the standard frame though.
