Confused Regarding 9mm Ammo for My M&P

[andy52]

They say a picture is worth a thousands words so here you can see the difference in the rounds.

The OP in this thread seems to have gone from a novice by his own admission (8 years ago) to helping a vendor test ammo in ballistic gel (as of his last post 5 years ago). Hope he is bearing up under the current ammo shortage...

If Protestant was on LuckyGunners ammo testing Team 4.5 years ago how could he not know the difference between 9mm ammo OR have the common sense needed to look each one up for him self OR ask LuckyGunner to explain it to him ?

Welcome aboard! As others have said, your pistol is chambered for 9mm (9x19) also known as 9mm Luger, 9mm Parabellum, 9mm NATO.

9mm Makarov is 9x18, typically used in Russian firearms.
9mm Browning is .380 ACP or 9mm Short, etc...

The different rounds available in 9mm Luger (9X19) can be overwhelming at first. I remember trying to sort it all out as a new shooter.

The general basics of 9mm (9x19)...(and if I'm wrong my fellow forum members will correct me).

The common projectile weights are:

• 115gr
• 124gr
• 147gr

The lighter the projectile weight, the faster it will travel given a standard charge. The lower the projectile weight, the slower it will travel given a standard charge.

Kinetic energy is dependent on speed and mass, so you're going to have to determine for yourself which projectile weight is compatible with your shooting preferences and intended use.

The projectile types I commonly encounter are:

• FMJ - Full Metal Jacket: round nose, flat nose.
• JHP - Jacketed Hollow Point
• LRN - Lead Round Nose
• HP - Hollow Point (may or may not be jacketed)
• TNJ - Total Nylon Jacket a.k.a. Nylock

LRN/FMJ are the least expensive. JHP's are more expensive.

The commonly found case types I encounter are:

• Brass
• Aluminum
• Steel Case (usually polymer coated)

Brass is reloadable. The other two are not.

I'm another new M&P owner and just wanted to say thanks, I found this post very helpful.
