Ian is correct and so are you! Both the C-96 and the luger ARE short recoil in operation. But neither one has a slide or a tilting barrel that locks into that slide. Barrels that tilt and move present difficulties when trying to squeeze the maximum accuracy out of them. Of course it can be done but it just requires a lot of extra work. With Lugers and C-96s you don't have to worry about things like slide to frame fit, or a tight barrel lockup, they can be remarkably accurate without doing anything to them because of that fixed barrel. My shooter grade C-96 can group 5 shots into an inch at 25 yards, two handed from a rest.
