Key differences include a slide stop, automatically locking the slide back when the weapon runs dry, a disassembly lever in the front section, safety in front of the trigger, rather than on the slide, and compatibility with a plethora of aftermarket modifications. While it is a different design from the N99, it uses the same gas-operated action, allowing it to use 10mm ammunition with ease. The 10mm combat pistol is a next-generation 10mm sidearm created before the Great War. For the unique version that appears in the Fallout: New Vegas Classic Pack and Courier's Stash add-ons, see: weathered 10mm pistol.For the unique version that appears in Fallout Shelter, see: Lone Wanderer.

For the suppressed version in Fallout 3, see: Silenced 10mm pistol.The number of manufactured pistols means that parts are easy to come by, however. Even damaged units can be used reliably, though they will offer subpar performance and jam frequently.

It remains a common weapon, as even though many civilian units were ruined, they can easily be restored by anyone with some repair knowledge. These features also make it popular with wastelanders, who appreciate the ease of maintenance. 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.
