Plasma rifle

From Memory Alpha, the free Star Trek reference.

A plasma rifle was a weapon used by many species. The weapons were used on the planet Earth during the mid-22nd century. This rifle modification of a plasma weapon was standard issue for the Earth Starfleet before the advent of the phase weapon.

These weapons were also used by human civilians of that era. A farmer named Moore owned a plasma rifle, which he carried to defend his property in Broken Bow, Oklahoma during a shootout between a Klingon and two Suliban. In the fracas, Moore used the weapon to incapacitate, and severely wound, the Klingon courier Klaang. This was the first contact between a human and a Klingon. (ENT: "Broken Bow")

In an alternate version of 1944, Vosk planned to deploy the soldiers of the Na'kuhl / Nazi alliance with weapons which he called plasma rifles. The weapons fired a modulating plasma pulse to destroy an American tank. Although they were powerful, they were also difficult to maneuver and required considerable amounts of energy. (ENT: "Storm Front")

This weapon was also refered to as a "plasma shotgun" in the script of "Broken Bow".

The Dominion made use of plasma rifles through its soldiers, the Jem'Hadar. (DS9: "Tacking Into the Wind")

It is likely that the Dominion's plasma rifles are more powerful than those used in the 22nd century by humans.
