How do you spell the gun sound pow?

There's no single "correct" spelling for the sound of a gun, as it's a very subjective and often exaggerated sound effect.

Here are some common spellings you'll see:

* Pow! - This is the most common and recognizable spelling, used in cartoons and comics.

* Bang! - This spelling is also quite common and reflects a more realistic sound.

* Boom! - This suggests a larger, more powerful explosion.

* Pfft! - This is more of a soft, muffled sound.

Ultimately, the best spelling depends on the context and the sound you're trying to evoke.
