The magazine-capacity champion of the day was the French вЂњUnionвЂќ autopistol in 7.65 x 17mm.

All of the above fired at about 700 R/M on full-auto fast, but not uncontrollable. An analogous system, still housed in the pistol grip, later showed up on the Czech вЂњSkorpionвЂќ machine pistols in 7.65 x 17mm Browning, 9 x 18mm Makarov, and 9 x 19mm Parabellum. The Spanish Astra Model F Broomhandle selective-fire clone dealt with the RoF issue by housing a flywheel system in its trademark вЂњblackjackвЂќ pistol grip that dragged on the underside of the bolt in recoil, reducing bolt velocity and thus RoF. Again, RoF was so hellaciously high that they decided it wasnвЂ™t worth the effort. The searage setup was different, with the regular thumb safety also functioning as the selector. In the 1930s, the Swiss WF:Bern built a couple of selective-fire M29 Parabellums in 7.65 x 21mm, with extended (16-shot) magazines and special wooden shoulder stock/holsters that housed the long magzines in the comb of the stock. RoF was in the neighborhood of 1,200 R/M, and DWM decided it wasnвЂ™t worth it. Naturally, it was based on the 8-inch вЂњArtillery ModelвЂќ with tangent rear sight, and was intended to be used only with the shoulder stock attached.

There was a sliding button up on the sear bar that, when slid forward, prevented the spring-rod from disengaging from the sear lever in the detachable sideplate, in effect disabling the disconnector, to achieve full-auto fire. There was an experimental selective-fire version of the P.08 developed at DWM before WW1 the Trommelmagazin 08 was originally intended for use with it.
