I LOVE This round. Very low recoil, good velocity. Why didn't this round take off sooner?
9MM Largo

You do know that this cartridge is 100 years old? For the early part of it's existence, it competed pretty well against 9mm luger.
It is a longer cartridge (costs more in material) that shoots bullets similiar to the 9mm luger and yet has less velocity, I think that it lost it's final battle when NATO countries adopted the 9mm luger as its standardized pistol/SMG round.
I never knew it took off. I assumed it was a deceased round. It's always been a known as a Spanish round with no real advantage over the 9MM. While the rest of the world was going with the 9MM Para, Spain went with the 9MM Largo (Long)
Not a good idea. From what I read the 9x19 is a much higher pressure round then the 9mm largo. And being shorter you will also have headspacing problems.
It is also my understanding that most spainish made guns(at the time) are not made of very strong steel. You could end up missing a few fingers or worse.

9x19 is a no-go in 9 largo. You can shoot .38 ACP in some of them safely, but that's an even more difficult round to find than 9 largo. .38 Super will usually chamber but it's running much hotter. Some Largo pistols are absolutely not safe with pressures of that magnitude. I've heard of people getting away with shooting super out of late model Stars, but I'm not going to try it. Esp. since the Star modelos are so #$@$ confusing.
That much is a myth. What they did do is chamber some pretty skimpy, archaic pistols in Largo. Think of it as a .38 S&W break top. Such a revolver is at its limit of pressure already, so if you put a higher octane .38-200 in there it can go kaboom. There are also some real tanks chambered in Largo, but figuring out which is which and what pistols had what mods done is way too complex for safety. Just shoot proper largo in them.

For the Largo fans, if you need ammunition, these guys have literally tons of the stuff, both corrosive and non-corrosive.

I have an Astra 400 that can shoot 9mm and .38 acp without any problems.
Some of the American made generic '.38 Super' stuff is pretty mild and is actually .38 acp marked as a Super load on the box and this shoots fine in my Astra but for liability I won't say that it comes in yellow boxes.
If you are a handloader, you can aquire a batch of .38 super brass, preferably brass and not nickle plated, and chuck them in a stationary drill to turn the semi rim down to the case wall and then cut a deeper extractor groove.
Run the drill at about 1200 rpm.
You can use a fine mill file to remove the excess case rim and a triangular or fine round needle file to deepen the extractor groove.
Case length is near identical between the Largo and the ACP/Super cases.
Actually a 9mm Largo is nothing more than a .38acp case that is made rimless like a 9mm Luger case instead of semi-rimmed and a .38 acp is nothing more than a 9mm Bayard with a semi-rimmed case head, but I digress.
Load with a 9mm Luger powder suggestion and use standard 124 grain 9mm bullets.
130 grain 9mm bullets work even better under the same powder charges if you can find them.
These handloads will work fine in 95% of the 9mm Largo pistols in the market. HTH

9mm largo is just another name for 9mm Bergmann, and later 9mm Bergman Bayard. It essentially the same case as the 9mm Steyr. It is a straight wall case, unlike the 9mm parabellum, which has a taper. Both 9mm Steyr and 9mm largo pistols can be converted to 9x19mm but it is rarely worth the effort. In its original loading, 9mm Bergmann was hotter than 9x19, however given the age of the early guns it is advisable to shoot mild loads. You should NEVER shoot 38 super. You can shoot 38acp in a 9mm Largo.
