I have a Grizzly Mark 1 in 10mm and I'm looking for a 45 Win. Mag. conversion, I found one but it doesn't have the slide. I was under the impression that all the conversions came with a slide but I may be off base here. If they don't how does it work with the different rim diameters?

I used to have a Grizzly and all available conversions: 45win, 357/45win, 357mag, 10mm, and 45acp. The conversions use the existing slide and just come with barrel, springs and magazine.

I really liked the gun but the grip was just too large for my hands, so eventually I traded it off.
