-Akimbo/dual wielding, perhaps only if each gun has a certain "akimbo" enchantment for balancing's sake (we all thought about this at one point when using em. right?)

-Compatibility with Guard Villagers mod, so the guards can use handguns (Might be something they would have to do on their end, but I am not sure).

-Having a chance for a skeleton to very rarely spawn with a handgun instead of a bow would just be a fun little suprise.

-Some sort of tactical vest and/or belt curio (stores unused and spent magazines in an inventory which the gun can pull from, and perhaps a way to switch out magazine types quickly for different situations?)

-Beam Bullets/Magazines: fires a beam of white, glowing particles that pierces through multiple enemies.

-Automatic Enchantment: hold down for automatic fire, but is less accurate and bullets disappear/have damage falloff sooner.

-Kitchen Bullets/Magazines: Crafted like normal bullets, but with sponges. Removes moss from mossy block variants, turns coarse dirt into normal dirt, and possibly more with other mods (snail slime, fallen leaves, and other ground cover blocks from other mods are blasted away, too.)

-Illumination Bullets/Magazines: crafted with torches, these bullets will place a torch on the surface they hit if it is valid.
