Since subsonic ammo is inherently less powerful, you could find yourself in a situation where a specific subsonic load in a specific gun with a specific suppressor won’t cycle the action on its own. In a semi-automatic firearm, there has to be enough power in the leftover gases to cycle the action of the gun. That extra cost adds up.Īnother drawback directly relates to one of the benefits listed above: recoil. With ammo prices the way they are right now, that definitely makes a big difference when picking up a few boxes here and there. Drawbacks of Using Subsonic AmmoĪmmo that is specifically made to subsonic specifications tends to be more expensive than its supersonic siblings. Subsonic ammo can also reduce some of the recoil, and when you pair that with a suppressor, it makes for a very pleasant experience if you’re introducing a new shooter to the world of firearms. When you pair a suppressor with supersonic ammo, that’s when you’re in for a real treat! The decibel level will be even lower and you’ll really see why the combo of a suppressor and subsonic ammo is so very cool. In a caliber such as 9mm, using a pistol suppressor like the Banish 45 will bring the decibels down to a hearing-safe level even with supersonic ammo. Obviously, the biggest advantage to using subsonic ammo is when you pair it with a suppressor. Anything slower than that is subsonic anything faster is supersonic.Īs a result, subsonic ammo is a specially calibrated load that is designed to travel slower than the speed of sound, thereby eliminating the supersonic crack. With an average air temperature of 68 degrees Fahrenheit, the speed of sound is 1,125 feet per second. The difference between something that is subsonic and supersonic all comes down to the speed of sound. When an object is moving slower than the speed of sound and doesn’t make that crack, it’s considered to be subsonic.

Couple Your Suppressed 9mm with Subsonic AmmoĪs was mentioned above, when something breaks the sound barrier and makes a cracking sound as it does so, that object is considered to be supersonic, moving faster than the speed of sound.
