I have a 45 cal P220 and would like to know if a 10mm Legion extended slide will fit and function on a P220 frame? Not sure if I could buy a Legion slide and barrel etc but thought it would be an interesting combination. Thank you.

The aluminum alloy frame of the P220 (.45) is not designed for the 10 mm, whether the 10 mm slide fits on it or not. All the 10 mm P220s have steel frame.

Thanks. I thought they might use the same frames.
