Sorry if this has been covered, but I couldn't find my answer with the Search function. I have a G30sf and a G29. I would love to have a G29sf by taking the frame from the 30 and using my G29 slide and barrel. Is this okay/safe to do? I figured they're the same size and shape, etc, so it should be okay, right? For the magazine differences I was thinking I would probably have to use the floorplates of the G30 mags in the G29 mags. Are there any problems that could arise from using the frame of a 30?
