Hi, I'm going to be getting one of these http://www.gunco.net/forums/f259/fs-...shipped-70597/ and am doing some planning. On a complete 1911 frame are the dimensions the same for .45, 38 super, 9mm, 10mm, .40, etc? I know a .45 would more than likely be simplest - but have noticed there are 38 super and 9mm parts out there - plus if one of these calibers are used then it looks like there is a 7.62x25 conversion as well (works with non ramped frames only - not sure the differences????) Like this one 7.62x25 Tokarev Barrel kit, 5 inch, for 1911 Gov't models in 9mm or 38 Super. New, by J&G Sales. That would be nice from an ammo standpoint.
