Hello,

Was just wondering if it is possible to convert a P220 chambered in .45 ACP to 10mm?

Can it be done with just swapping barrels and recoil spring? Or would this be possible with buying a complete slide and barrel in 10mm?

Has anyone done this? Is it even possible?

I have a 2006-2007, milled slide version of the P220.

Thanks for your replies in advance.

I believe the 10mm requires a steel frame. Is your model alloy or steel?

Thanks for the replies.

I really wasn’t sure about the frame. Makes sense it would require a steel frame, which mine is not.

Guess it will be a complete gun purchase for me. Lol
