Laser pistol was a broad designation encompassing multiple models of portable blasters.
In the initial Star Wars movie's screenplay, the phrase "laser pistol" was employed to describe a range of weaponry wielded by characters like Princess Leia, Ponda Baba, Han Solo, and Luke Skywalker. This terminology appeared exclusively in the action's descriptive text, never in spoken lines; consequently, it's absent from the final film, which favors "blaster" as the common, in-universe word.
The phrase, along with variant spellings like lazerpistol and lazer pistol, was present in earlier versions of Episode IV's script.
In 1977, Kenner manufactured a toy labeled a "laser pistol" as a component of its initial Star Wars toy line. This toy was based on Han Solo's pistol as seen in A New Hope.
