Rounds fired from a 37mm/40mm launcher are not only much larger, but much more effective. Popular launchers include the M79-LF, which has a folding stock and only weighs 5 pounds. Other popular launchers include those manufactured by Smith & Wesson, and the ARWEN (Anti-Riot Weapon Enfield) launcher.
The rubber ball munitions in 37mm/40mm offer either 175 or 225 .32 caliber balls or 27 or 42 .60 caliber balls, depending on casing size. In addition, there are bean bag rounds (capable of firing No. 9 lead shot filled bags 200 feet per second), sponge grenades (used as a kinetic weapon or with CS), liquid filled chemical rounds (filled with OC, CN, or CS), and distractionary rounds (flash bangs). CTS, MK Ballistics, and Federal Cartridge are among the many brands in production.
Another less-lethal platform that's very effective at quelling prison riots is the hand-held grenade. These include "Stinger" grenades, which disperse .32 caliber rubber pellets in a 50-foot diameter pattern, Stingers with OC, smoke grenades, gas grenades (CS, CN, or OC), and flash bang grenades (which produce a 2,420,000-candle flash and a 174.5-decibel bang at 5 feet) to disorient a subject.
Like any other tool, the above listing of less-than-lethal weapons, equipment, and protective gear all have their limitations. No item will be 100 percent effective at all times.
However, manufacturers have responded magnificently to the needs of today's corrections officers. With proper training and usage, these devices will continue to keep inmates safe and manageable and officers safe and sound for a long time to come.
