A device designed to reduce the acoustic intensity of a firearm discharge when affixed to a pistol chambered in 5.7x28mm ammunition minimizes the audible signature of the shot. These devices function by capturing and slowing the expanding gases produced by the firing of a cartridge, thereby decreasing the pressure and velocity of those gases as they exit the firearm. A practical example involves using such a device on a FN Five-seveN pistol to make it more hearing-safe for the shooter and to reduce the risk of alarming others in the vicinity.
The advantages of utilizing such an accessory extend beyond simple noise reduction. Decreased recoil can lead to improved accuracy and faster follow-up shots. In certain applications, this enhanced control is crucial. Historically, these types of firearm accessories were primarily developed for military and law enforcement purposes, emphasizing covert operations and tactical advantage. Over time, their appeal has broadened to include civilian shooters seeking enhanced firearm safety and performance.
