eaa witness poly

I just ran across a 9mm eaa witness poly for a price I could not pass up ($225otd w/ 3 mags). I was wondering if the poly witness can change between calibers like the steel frame version?

All depends on if its the small frame (no) or the large frame (yes, if you don't mind the slide at the back being too short for the contour of the poly frame).

its a large frame! hmmmm there may be a 10mm in my future;)
