The Remington 870 pump-action shotgun is, without a doubt, the law enforcement shotgun, with more than 80 percent of agencies at all levels using them. In April of 2011, Remington in fact produced its 10 millionth 870 since it started making them in 1949. They are also extremely durable, which doesn’t give police armorers that much to do when it comes to repair them.

Nevertheless, routine maintenance and inspection is key to maintaining any piece of equipment, and the 870 is no exception. This is why a dozen officers from state, local and federal agencies attended the free armorer certification course conducted by Remington at the National Rifle Association’s headquarters in Fairfax, Virginia, recently. This school was one of several sponsored by the NRA’s Law Enforcement Division (LED) as part of their commitment to supporting police training.

Each student provided their own 870 shotgun for this two-day course, ranging from short-barreled entry guns to extended-magazine tactical models to some that looked like they carried a lot of history. According to the instructor, Dewayne Mounce, 870s have a tendency to last, and he recently had seen some built in the 1950s that were still in FBI use.

Students learned to conduct safety and function checks, completely disassemble the guns, diagnose issues, and perform maintenance and replacement of parts as needed. Remington also provided ten shotguns in various states of disrepair, which the students then inspected, identified malfunctions and repaired. Mounce, a 17-year Remington veteran, works with a handful of other Remington armorers to teach this course to more than 2,500 officers each year.

Free NRA-LED armorer schools are open to public and private law enforcement officers and the military. Due to limited space, however, slots are assigned by random drawing. To learn more about NRA law enforcement training and available courses visit
