Medusa multi caliber revolver

[two70]

I hear that guns chambered for 9 MM Parabellum (9x19) will also fire 9 MM Makarov (9x18) and .380 (9x17) as long as the extractor holds the case against the breechface.

The 9mm demonstrations start at about the 8 minute mark.

Good that you asked... DO NOT mix russian and non-russian similarly-named calibers. Russians measure by the lands, almost everyone else measures by the grooves. Russian 9x18 mak and 7.62x54r bullets are several thousandths larger than non-russian calibers like .380, 9x19, and 7.62x51. (.365 vs .355 and .312 vs .308) While .380acp can chamber and fire in a 9mm gun (though it might not cycle), 9mm mak probably won't go into battery and if you force it, has a good chance of over-pressuring.

I didn't say it was a good idea.

I would buy a Medusa if it was in some godawful Russian caliber, I would buy it today.
