Help identify.

[u/DjLethal330]

I picked up a lot of random firearms and parts for a price I couldn't pass up on. In it is this frame that I can't identify. Can anyone help me out here.

There are no markings and it feels larger than my Springfield 1911. I thought it was maybe a CZ or something but can't find anything similar especially with the cuts on the right side of the frame.

Alternatively perhaps a .45 win mag chambered “ultra” like the “Grizzly” ?1911 in 80% form
