Common and Reliable Firearms
This document is designed to provide rules for firearms that are reasonably common and widespread. Firearms are implied to be an alternative to bows and crossbows, not mysterious devices that only a couple of people in the whole world use.
Firearm Proficiency
Firearms are considered ranged weapons and proficiencies are granted accordingly. Some classes get additional proficiencies.
Bard: Heavy and Light integrated pistols.
Rogue: Heavy and Light integrated pistols.
Sorcerer: Simple firearms.
Wizard: Simple firearms.
Ammunition
Firearm ammunition costs 1gp per 20 rounds, all firearms consume 1 round per attack except for the Duckfoot pistol, which consumes 5. If you are proficient with a firearm and either Tinker's Tools, Jeweller's Tools, Smith's Tools or Alchemist's Supplies, during a long rest you can produce 20 rounds of ammunition for that firearm from materials worth 5sp.
Firearm Properties
Loud: Your weapon rings with thunder that is audible within 300 feet of you whenever it makes an attack.
Reload: After you make a number of attacks equal to the number listed in parenthesis, you need to reload your weapon by either not moving for a turn or using a bonus action.
The weapon is considered to be reloaded if you made an attack and haven't moved on the same turn.
Long Reload: Same as Reload, but you need to either not move and use a bonus action, or use an action to reload.
Snubnosed: Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls made with this weapon
Scatter: Scatter lists three numbers: first one is the weapon's Point Blank range in feet, the second one is its Normal range, the third one is its Long range.
When you make an attack at a target within Point Blank range you can roll an additional 1d4 if the weapon is simple or 1d6 if it's martial, adding the number rolled to the damage.
When you attack a target out of Point Blank range you can target an additional creature within 5ft of the original target. Use the original attack roll, but roll the damage separately.
When you attack a target out of Normal range you have disadvantage on the attack roll. You can’t attack a target beyond the weapon’s long range.
Wide Scatter: When you attack with this weapon, instead of targeting a single creature, you target all the creatures in a 30 foot cone. Every creature within the cone must succeed on a Dexterity Saving Throw or take the attack damage.
Matchlock: The construction of this weapon is simple enough that it can be made as a matchlock, reducing the price to the one listed in parenthesis. Because the match on a matchlock firearm has to be lit in order to fire, you can not use this weapon on the same turn as unholstering it. Alternatively, you can use a bonus action to light it, allowing you to shoot.
Variant: Hardcore Matchlock
Any matchlock firearm has a 25% chance (1-5 on your attack roll) of not firing in heavy rain, and a 10% chance (1-2 on your attack roll) of not firing in light rain. If your firearm misfires, the round remains in the barrel and can be fired again.
The match can remain burning no longer than 10 minutes before needing to be replaced as an action. 1 hour worth of match costs 5gp
The smell of a burning match can be detected downwind with a Wisdom(Perception) check. DC depends on the range and other circumstances.

Firearm Modification
Multiple barrels: Some firearms can have multiple barrels attached, instead of one. Such firearms lose the Matchlock property and their price, weight and Reload or Long Reload score is multiplied by the number of barrels. Different types of firearm can have different amount of barrels attached.
Four barrels: Pistol, light pistol, palm pistol.
Three barrels: Carbine, arquebus, shotgun, dragoon pistol.
Two barrels: Blunderbuss, blunderbuss pistol, musket.
Lorenzoni system: Firearms can be made with an integrated magazine for powder and bullets that allows for a much greater amount of shots before reloading, called a Lorenzoni system. Only the most skilled gunsmiths can create such firearms.
Any firearm with a Lorenzoni system looses its Matchlock property, its Reload property gets replaced with Long reload(8) and price increased by 500 gp.
Eligible firearm types: Pistol, light pistol, palm pistol, dragoon pistol, carbine, arquebus, musket.
