I concluded that I’d rather not be shot with a 9 x 18.Īs far as multi-caliber capability goes, I once verified that. I used 9 x 18 exclusively in such pistols, and found that they gave very good accuracy and reliability and had terminal effects not much less than 9 x 19mm, roughly in the range of. The main result was poor accuracy due to the bullets tending to “skate” down the rifling, and occasional smokestack jams due to the recoil springs being balanced for the greater recoil energy of the 9 x 18 rounds. So a lot of people just used inexpensive, non-corrosive U.S. But most 9 x 18 ammunition was either corrosive-primed Chinese or PriviPartizan non-corrosive the Chinese was easy to find and cheap, the P anything but. when 9 x 18mm Mak pocket pistols like the FEG R-61 and PA-63 Walther clones were a lot cheaper than. The most significant question, of course, is how many people would actually have a need for such a system, beyond simply thinking it is cool (and if the multicaliber capability makes up for the finicky loading, extraction, and accuracy).įor a more detailed look at the history of the Medusa, I recommend this article by AirborneCombatEngineer. The last two obviously did not engage the rifleing as they are substantially smaller than the bore, but the fire safely regardless. 380 Automatic, 9x20mm Browning Long, 9×19 Parabellum, 9mm Largo, 7.62mm Tokarev, and. They are, however, also the weak point of the gun, as they are pretty much the only fragile component, and since the company quickly went out of business, replacements are completely unavailable. These fingers allow proper indexing of virtually any cartridge that will physically fit. It uses long flexible fingers which snap into the extractor grooves on rimless cartridges or can be depressed down away from the cases of rimmed cartridges. ![]() Jonathan Phillips solved this problem with his 1995 patent for the extractor mechanism that is the fundamental heart of the Medusa revolver. What makes it difficult, is finding a way to hold a variety of different cartridges properly in position for reliable firing and extraction. This is made possible because a revolver does not have the headspace requirements of a semiautomatic handgun, and the barrel doesn’t know one type of bullet form another, so long as they are not larger than the bore diameter. The cartridge is now obsolete, but Fiocchi Munizioni occasionally produces batches.The Phillips & Rodgers M47 Medusa is a mechanically very interesting firearm a revolver that can chamber basically any cartridge with a 9mm bullet diameter and an overall length no longer than a. This means that 9mm Glisenti cartridges will chamber and fire in 9×19mm firearms, at the risk of non cycling properly and causing malfunctions, but it also means that 9×19mm cartridges will chamber and fire in 9mm Glisenti, presenting a significant risk of catastrophic failure to the firearm, and a risk of injury to the shooter. However, the powder charge of the 9mm Glisenti cartridge is reduced compared to a typical 9×19mm cartridge, creating it significantly less powerful, as it is for also meant to be used in blowback pistols, which are easier and less expensive to manufacture than locked breech firearms. The cartridge was based on the German 9×19mm Parabellum in fact, both cartridges are dimensionally identical. The Medusa M47 revolver can also fire 9mm Glisenti ammunition along with numerous other. It was also used in other Italian weapons such(a) as a Beretta Model 1915 and Beretta M1923 pistols, the OVP and Beretta Model 1918 submachine guns, and the Villar-Perosa aircraft submachine gun. The 9mm Glisenti was developed for a Italian Glisenti advantage example 1910 pistol, number one used in World War I. The 9mm Glisenti is an Italian pistol in addition to submachine gun cartridge.
