9mm Luger/ 9mm parabellum?

[Flowmini98]

Real NooB question here but whats the difference between 9mm Luger and 9mm parabellum and 9mm ????
And which one can be shot through a stock Springfield XD ? Also what will the different " grain " do for me?

[NapaCountyShooter]

Same thing. Put either through your Springer.

[1nickatnite1]

they're the same thing, 9x19, and yes they can be shot through your xd. Google is going to be your friend when it comes to these questions. 9mm comes in 115 up to 147, 115 is great for plinking and practice but i use 147 federal hsts for hd.

There is no difference as long as you pay attention to the measurement expressed as 9x19MM. Look up my the quote on the first line, and it should shed some light.

More grains = More Boom = Faster bullet

^^For some reason, I associate grain with the powder charge. Need to read up on them books...thanks to those who caught on...probably should stay away from reloading until then

Less grains = Lighter Bullet = Faster Bullet

9mm Parabellum was the the original designation as the round was invented as a military cartridge in 1908. It's metric designation is 9x19mm and the original design bullet weight was 124grs. The pistol it was designed for was the P-08, which Americans called the Luger...after it's designer George Luger.

That is how it came to be referred to domestically as the 9mm Luger cartridge...there is also a .30 Luger.

The 9x19mm has been loaded with bullets weighting 90grs, 115grs, 124grs, 127grs, 135grs and 147grs. Maintaining the same case pressures, the lighter bullets will give you more muzzle velocity

9MM Luger
9x19
9x19 NATO
9MM Parabellum
Just 9 or 9mm commonly used.

All the same thing.

Typically, lighter bullets also hit lower than heavier ones.
You might find that your sights are perfectly aligned with 115g but hit somewhere else with 124g.
You should try different bullet weights in your gun to see what it likes best.

Last time I saw a thread like this someone posted that there were 61 different types of 9mm.

Wiki - 9mm

As noted above the terms are interchangeable, but . . .

"Parabellum" is much cooler, being Latin and meaning "for war"

"Luger," in contrast, sounds like something that comes out of your nose.

I don't know if this is true anymore, but back in the day, we were told to check any surplus 9 MM ammo and make sure it was not made for use in sub machine guns. This was told to me by a gunsmith that I asked to examine a cracked slide on a vintage Wather P38. He claimed high pressure 9 MM "submachine gun" ammo could do that to the slides on a P38.

some earlier weapons were not designed to fire high pressure rounds
but a XD is safe to use +P.

Luger is the last name of the German guy who designed the 9mm Parabellum.

More grains = More Boom = Faster bullet

This way or may not be correct.

"grain"is a measurement of weight, there are 7000 grains per pound. I'm guessing, like everything in the Imperial Measurement System, it was based on how many grains of sand the King of England could hold in one nostril.

The bullet (the projectile) is measured in grains. In 9mm luger/parabellum, it is TYPICALLY 115gn, 124gn, 147gn for commercial loads in round nose profiled bullets.

However, the powder charge is ALSO measured in grains.

The statement "More grains = More Boom = Faster bullet" is correct if it refers to the powder charge, but the box of ammo you are buying will NOT mention this, it will mention the weight of the bullet. In fact, lighter bullets actually use more powder (because the bullet is smaller, you can get more powder in there, and also you don't hit max chamber pressure as quick).

Since lighter bullets with more powder travel faster, that statement is actually wrong if you are talking about bullet weight.

Example. I load 115gn bullets with 4.6 gns or W231, but 124gn bullets get 4.3gns. The heavier a bullet is, the LONGER it will be (since the diameter is fixed) and the longer it is, the less case space you can put powder it, because the entire cartridge must still fit into your magazine.


ANYWAY, the bottom line, for 9mm is generallly this ... the heavier bullets (147gn) give you less felt recoil, but you'll also notice that your slide is a bit slower, so your gun is ready to shoot a touch slower. A lighter bullet is "snappier" and you'll feel a touch more recoil, but the gun goes into battery faster. This is not relevant to most people except for expert IPSC/USPSA shooters who have to take fast double tap shots.

Some guns like some weights better than others, but in general you'll probably not notice, but you can try different bullet weights for kicks and maybe you'll find a sweet spot for your gun.

Also, read the owners manual.

This is not accurate. The "grains" displayed on the box of ammo refers to the weight of the projectile, not the amount of powder.

Therefore more grains=heavier bullet=slower bullet.

Also, Fiocchi makes a 9mm cartridge in 158 grains...

Duo'h. Thanks for the clarification. Will adjust post to reflect.
