Sig p220/220 9mm conversion??

[FrankDux]

Sorry if this is a stupid question, but i was thinking is it possible to convert p220 .45 to 9mm using a Two Step Caliber X-Change Kit, and use the p220 9mm mags? Just a thought.........

if you're talking about a complete top end switch...you'd still need a 9mm ejector/slide lock and a calibre appropriate locking block
