I'm asking for a close friend. He owns an ols star 9mm Largo. He also knows that it is technically a 9mm magnum. He asked me if there were any bolistic similarities and I'm not sure so hence my question. 0 -
Not even close ballistically. The Largo is a Spanish, military pistol and submachine gun cartridge dating to the early 20th Century. It's 9mm bullet max's out between 1100 and 1200 fps depending on the platform.
The 10mm dates to the 1980's, with factory ammo at 155 grains, approximately 1300 fps. There are many different bullet weights besides the 155 grainers, some way hotter then 1300 fps.0 -
Further, it is hardly a 9mm Magnum unless you're considering dimensions being larger than a 9X19 as being "magnum." It's a very close round to the .38 ACP, but is NOT in the .38 super class (which will damage the gun if fired in it). 0 -
Kind of like comparing a 1953 Chevy with a 2011 ZR1 Corvette.
And your friend doesn't know squat if he thinks it is a "9mm magnum".

NOW LISTEN! I asked an honest question and for someone else no less. I have always appreciated information found here on Gunbroker but what I didn't need nor want was a verbal online thrashing. I have always respected everyone here on the forums and ask the same of everyone else. That being said, I do appreciate the knowledge that has been shared regarding the two calibers. Now I can pass it on to the my friend. Thankyou to all. 0 -

Different.
Ballistically, the standard 9mm largo load is roughly equivalent to a standard 9mm luger. Even though it runs from a slightly longer case, it takes the same .356" bullets as 9mm luger, and doesn't spit them out any faster.
So the largo round falls short of .357 magnum. It also falls short of 357 SIG (auto) and 9x23 Winchester, each of which might more properly be termed a "9mm magnum" (especially the 9x23).
10mm, obviously, takes a 10mm (or .40") bullet which is both wider and heavier than the 9mm, and it fires it faster. So its quite a bit more powerful than the largo, and roughly comparable to a .41 magnum.0 -
Howdy Garth,
DANG RIGHT you asked an honest question. Though having much material-- books, manuals, articles, etc, from collecting cartridges for years, close at hand by the computer is Frank Barnes 6th edition of "Cartridges Of the World". Which I picked up to see if could add to help out. Well, looky that... he does not even list the Largo.
If everybody knew it all, like some self appointed know-it-alls seem to want us to believe, then this forum would not even exist, now would it??????? geezeus
So, with my mini-rant feeding a troll over and done, glad you did get the info asked for.

I gotta go with 45er on this one, IMO Garth got mistreated like a new shopper in a gun store populated with veterans of the hot stove league. Makes folks wonder why they even want to ask when this stuff happens. 0 -
Thankyou sirs, beantown and 45er! 0 -
Thankyou Riomouse911! Good to know some people know how to treat others with diginty and mutual respect. You three are certainly a friend to me. 0 -
Who was it that made 9mm magnum back in the day? LARS? Any ways I always thought the 9mm magnum was a rimless .357 magnum. Now we all know 9mm and 10mm is 1mm difference. If the Largo was really a magnum or close I'd still say the 10mm has a bit more powerful Kung Fu. 0
