    I'm a Sig fan, though I have many other pistols. I shoot Sigs almost exclusively. I want to turn a 220 into a 10mm or 45 super. I can put 9 rounds of 10mm in a 8-round 220 mag. Those 9 rounds seem to fit and function well. Can I get a 10mm barrel for the 220? If I can't, what do I need to make the 220 into a 45 super? Do I need another barrel? Of course I'll need heavier recoil springs. What else would I have to do to a 220 to make it a dedicated 45 super? Any thoughts?

    Good idea! I'll give it a try.
