Musket

From Memory Alpha, the free Star Trek reference.

A musket is an antiquated form projectile weapon developed and used on Earth. It was loaded with gunpowder and a lead ball, the latter of which was the projectile fired. They may also be equipped with a bayonet attached at the tip of the gun's muzzle.

In the mid-19th century, Charles Darwin was noted for sailing aboard the HMS Beagle without a single musket on board. (Star Trek Nemesis)

In 2365, the crew of the USS Enterprise-D were whisked away by Q to an unknown planetoid where they discovered aliens wielding muskets and dressed in 18th century French army uniforms. Both Worf and Wesley Crusher were killed after being pierced with a musket's bayonet, but were revived by William T. Riker, who had been temporarily granted Q's abilities. (TNG: "Hide and Q")
