I've wondered about the 10mm...my newest trinket is a TZ-75 chambered for 9mm with a second barrel and slide that allows me to also shoot the .41 Action Express round which is made on 9mm brass,so the extractor still pulls 'em out perfectly without any need for anythimg more than a barrel swap and a mag full of the wildcats. I'm not very familiar with the 10mm round. I passed up a sweet, tricked out Commander a few years back and am still kicking myself over not snagging it. Hard to believe something designed roughly a century ago can still be so capable so long afterwards; look at a camera from 1911--it's a dinosaur!
I'd love to see a re-shoot on this with the mag in and the 10mm casing substituted for a .45 ACP casing. The slightly higher viewpoint would really help solidify the basic shot, I think.
