According to the official C.I.P. (Commission Internationale Permanente pour l'épreuve des armes à feu portatives) guidelines, the 9×21mm case can handle up to 235 MPa (34,100 psi) piezo pressure. In C.I.P. regulated countries every pistol cartridge combo has to be proofed at 130% of this maximum C.I.P. pressure to certify for sale to consumers.

2008年1月30日 · They are really stupids, as the 9x21 has in fact the same overall dimensions as the 9 Parabellum. Anyone can know that's not 9 Largo just with a quick look at the cartridge. It's just a 9 Parabellum cartidge with a 2mm longer case covering the bullet.

2005年7月2日 · Is the 9mm largo the same as 9x21? Seems all are pushing 9mm [or close] at high velocities. The 357 sig is the most recently developed and most compact. Doest it "fit" in the same category as the others mentioned? .38super is a semi-rimmed cartridge. I believe it uses 9mm (.355?) bullets.

By 1913, 9mm Largo loads had a bullet diameter of .355, or the same as 9x17mm, 9x19mm, 9x21mm, and the other 9x23mm cartridges. After WWII, 9mm Largo loads often pushed a 125gr bullet as fast as 1,200 fps, which raises pressures past the 35,000 psi mark.

2023年5月3日 · 9mm Largo is a 9x23 not a 9x21. Yes, Starline has made 9mm Largo brass. It can be loaded with 9x19 (Luger/Parabellum) dies or 38 ACP or 38 Super dies. With the 9x19 dies you just have to adjust the length appropriately. Tim

2017年1月31日 · Since Starline started making 9mm Largo cases, I have put all the .38ACP/Super and 9x23 cases away and only use the right sized cases. BTW, RCBS has a die set labeled as for 9mmLuger/9x21/9x23 (part number 20515) that works perfectly for the Largo but is less than half the price of a set labeled for the Largo.

2021年7月4日 · I think the 9mm Largo is something like 9x17 OR 9x18. EDIT: the 9mm LARGO is a 9x23 brass. Longer than the 9x19 (LUGER). The 9mm, as we often call the 9mm LUGER, is 9x19. There are also 9x21, 9x23 and the 9x25. There are probably more than I even realize. Ya gotta me careful when ordering stuff, as you have already discovered.

2009年11月6日 · Well, let me tell you that I have MANY handguns in the 9mm, 9x21, 9x23, 357SIG and .356TSW caliber loadings. Usually the 9x21 is loaded to a much higher pressure …

2024年3月21日 · The 9mm Largo is making a comeback in some circles. This is similar in its dimensions to the 9mm Steyr, which makes it a good option for a lot of people. The cartridge …
