When I spoke of a barrel that was not ramped, I meant one that did not require milling the frame for the special integral ramp barrel type that became popular with the ground shaking loads used in 38 Super "Race Guns" to "make major." My "kit gun" frame was originally intended for building as a 45 if the included magazine meant anything, but I want(ed) to make it possible to shoot 9mm in it by making a complete 9mm top (with a barrel having the original style link mechanism) then adapting the frame by adding the (necessary) 9mm ejector pinned to the top of the frame and changing the magazine. I have done this with a standard single stack frame (aluminum, made by AMT, IIRC) and had no problems. My question was whether the same would be true for the Para double stacker, and although the mags may be a bit of a challenge to find, the rest looks do-able. I guess the only question now is whether I want to. :hrm:
Thanks again to those who responded with information and opinions.
