45 barrel, even if relined (which it of course has to be) leaves too much of the lower arc of the 7.63 case head unsupported, which can lead to bulged or burst cartridge cases. 45-sized pin and hole leaves too much of the primer unsupported and can lead to blown primers with the 7.63’s higher breech pressure.Ģ. The firing pin on the Super is smaller in diameter, with a smaller breechface hole. In his book Pistolsmithing, George Nonte stated that to convert the 1911 to 7.63, you need to start with a. 45 magazine would hold about 30 9mms, and the longer 30-round box would probably hold about 40 or so.īallistically, it wouldn’t be far behind the 7.62 x 39, and that would make it a pretty serious law-enforcement long arm for “in-town” use. Not to mention greater magazine capacity a 20-round length. 30 Carbine doesn’t need a platform as heavy a the “Tommy”, and the high-velocity 9s would get the most advantage from its longer barrel. If I could have a Thompson in any caliber I wished today, my choice would probably be something like 9mm Winchester Magnum or the old 9mm Mauser Export. That one could easily be recognized by its 24″ barrel and the tubular buffer assembly that stuck out 5″ behind the receiver, making a proper cheek-weld on the standard Thompson stock just about impossible. 351 WSL (my choice for the most interesting idea), and a single “Ersatz BAR” in. I think 7.63 was about the only caliber Thompsons weren’t made in, at least in prototype form.Īccording to an article in Gun Digest a few years ago, Auto-Ordnance and Colt made prototypes in 9 x 19mm. This Shansei Broomhandle is one from the relatively recent commercial batch, which should make it more affordable and less worrisome to shoot than the nearly 100-year-old originals. They are actually the same basic size as the C96 (and retain the 10-round capacity), but are much wider and heavier. A few thousand of these were originally made in Shansei from 1928-1931, and then another batch was made for export in the 1980s. 45 ACP cartridge also became popular with Thompson submachine guns in some areas, and the natural result was a Chinese arsenal designing and producing a C96 Mauser pistol scaled up to use. The C96 “broomhandle” Mauser in particular was popular, and it was copied by a number of Spanish firms for sale in China as well (in fact, the fully automatic Schnellfeuer version was initially made by Mauser specifically for Chinese sale). During the Chinese civil war in the 1920s and 30s, international arms embargoes made rifles difficult to acquire – which led to a lot of popularity for pistols with shoulder stocks.
