An MiB Agent's Pistol was a standard field weapon. It's firepower had the capacity to disintegrate partial or entire lifeforms. Though what it lacks in power this weapon makes up for in its inconspicuous nature that makes it the perfect sidearm for most missions. Additionally, all agents are trained in how to switch rounds from primary fire to "Alkali" when a single weapon is the difference between life and death-by-acidic-goo. It was standard issue since 1995.
