9mm Ammo

Ammunition Depot is one of the only places that will take returns on 9mm ammo purchased from us. Check out our return policy at Ammunitiondepot.com/content/9-shipping-and-returns .

There is no real expiration date for 9mm ammo. If you keep it stored in the correct conditions (cool and dry) it can last over a lifetime! For more information check out our article “How to Store Ammo” here.

The difference between the two is the weight of the projectile measured in grains. One grain is equal to 1/7000th of a pound. The 9mm 115 projectile weighs 115 grains and the 9mm 124 projectile weighs 124 grains. Different grain weights will have different muzzle velocities, energy, and terminal ballistics.

9mm subsonic ammo is ammo that travels slower than the speed of sound. The speed of sound is roughly 1,100 feet per second. This number could vary based on barometric pressure, temperature and humidity. Most 9mm ammo travels faster than the speed of sound but there are some options that travel slow enough to be subsonic. This ammo usually has a heavier projectile around 147 grains or more. The desire for subsonic ammo is that it does not create the sonic boom that an object traveling faster than the speed of sound will. Most often subsonic ammo is used in conjunction with a suppressor (AKA silencer).

9mm ammo with low recoil will be advertised that way. Look for ammo that says low recoil or lite on the box. For example: Federal Hydra-Shok 9mm 135 Grain Low Recoil JHP or Hornady Critical Defense Lite 9mm Luger 100 Grain FTX. Low recoil ammo will generally be easier to shoot and allow for quicker target reacquisition for follow up shots.

9mm hollow point ammo is the best choice for self defense with a 9mm firearm. Hollow points expand on impact creating a larger wound path and expending maximum energy in their target. They are also less likely to over penetrate causing you to strike an unintended target. For more information check out our article "Why Hollow Points Are the Best Choice for Self Defense" here
