In the anime

Weaponry, mainly firearms, have appeared in the anime numerous times. While there is generally no concern with this as weapon use is rather mild, an extreme case caused one episode to be banned. Weapons in the anime were a common occurrence in the first half of the original series, but when the Johto League story arc premiered, all kinds of real-life weapons were practically absent from the show, aside from weapons associated with Team Rocket's mechas.

Weaponry continued appearing from Pokémon the Series: Ruby and Sapphire onwards, though less often.

In Pokémon designs

Pokémon themselves are the primary reason weaponry is sparse in the Pokémon world: Pokémon battles are the main method of fighting, and thus Pokémon themselves can be considered the weapons. In fact, early design documents for the first Pokémon games mentions that they considered having trainers fight alongside their Pokémon, but this was removed because "If you can fight on your own, what’s the point of having Pokémon?" ^[1]

However, many Pokémon use held tools, and a portion of these can be classified as weapons. Others are modeled after real-world weaponry.
