This includes both clearing misfeeds and restoring a unit to working condition after long exposure to elements without maintenance. It can also be repaired easily by anyone with even the most basic technical knowledge. The pistol is designed to withstand the most extreme conditions, which was one of the requirements for a new service sidearm. The long-barreled pistol remained in service for 26 years, until the Great War destroyed the United States. The large-framed, gas-operated N99 was selected as the standard issue conventional sidearm of the United States military, following the phaseout of the N80 in 2051.
