Autofire fire) All firearms do piercing damage. *Damage s by range increment. Shotguns do no damage beyond the third increment Autofire: You may attempt two extra attacks per round with a weapon that has autofire. The extra attacks are at your highest base attack bonus, but with each attack (the extra ones and the normal one) suffers a -6 penalty. You must use a full attack action to use autofire. The Multishot feat reduces this penalty by 2. Each autofire attack uses three bullets. Multifire: You may attempt one extra attack per round with a weapon that has the multifire capability. The extra attack is at your highest attack bonus, but each attack (the extra one and the normal one) suffers a -4 penalty. You must use a full attack action to use multifire. The Multishot feat reduces this penalty by 2 2. Standard: You may attempt one extra attack per round with a weapon that has the multifire capability. The extra attack is at your highest attack bonus, but each attack (the extra one and the normal one) suffers a -6 penalty. You must use a full attack action to use multifire. The Multishot feat reduces this penalty by 2 2. Reloading Firearms: It takes a full round action to reload a firearm. Granular Reloading Firearms Loading Method Time to Reload Belt 2 rounds to load a belt and chamber a round Drum 2 rounds to load a drum and chamber a round Break-Open 1 round to load up to two cartridges, or 1 round to load all chambers if a speed loader is used Clip 1 round to load a clip and chamber a round Magazine 1 round to load a magazine and chamber a round Side 1 round to load two cartridges Swing-Out 1 round to load up to two cartridges, or 1 round to load all chambers if a speed loader is used Firearm Malfunctions (optional): On a natural 1 on an attack roll, firearms may malfunction. Roll 1d20. If the result is a 1, the ammunition has misfired (a dud). If the result is a 2, the weapon has jammed. It takes 1 round to clear a jam or misfire. A follow up die roll is required to clear a jam. If you roll on 1 on this follow up roll, the weapon suffers a serious malfunction and cannot be readily repaired in the field. Weapons that are in poor condition or are very dirty have a higher chance of jamming. In general, such weapon will jam on a 2 or a 3. Some weapons may be more or less reliable than standard. Handgun/Submachine Guns Range: Handguns and submachine guns typically have a range increment of 20 ft. It may vary as much as +/- 10 ft depending on the individual model (however, this is more in-depth than this document is meant to be).

Caliber Buckshot Damage Birdshot Damage Slug Damage Critical 10-gauge .3d8/2d8/1d8 3d4/2d4/1d4 2d10 x3 12-gauge 3d6/2d6/1d6 3d3/2d3/1d3 2d10 x4 16-gauge 3d6/2d6/1d6 2d3/2d3/1d3 2d10 x3 20-gauge 2d6/1d6/1d4 2d3/1d3/1d2 2d8 x3 28-gauge 2d4/1d4/1d3 2d2/1d2/1 2d6 x3 .410-gauge 1d8/1d3/1d2 1d4/1/1 1d10 x3 Ammunition Hollow-Point: Against unarmed targets, increased critical multiplier by 1. Against armored targets halves damage and lowers critical multiplier by 1. Armor-Piercing: Reduce armor bonus by 3, but -2 to damage and critical multiplier is reduced by 1. Accessories Bayonet: When affixed: 1d6 damage, 19-20x2. Piercing and slashing; +2.5 lb. Unaffixed: 1d4 damage, 19-20x2. Piercing and slashing; 2.5 lb. Bipod: After bracing for one round, applies a +2 circumstance bonus to attack rolls. Flash Suppressor: Normal Spot DC to see muzzle flash is 10 (0 at night). Spot DC with flash suppressor is 20 (10 at night). Folding and Telescoping Stocks: Reduces the overall length of the weapon (there are no rules for how this might benefit the weapon in the standard rules, but Star Wars Saga allowed weapons with folding stocks to count as pistols for the purposes of proficiency). When folded, applies a -2 circumstance penalty attack rolls. Laser Gunsight: Grants a +4 equipment bonus to attack rolls. A Spot check (DC 15) allows the target or someone within visual range to notice the red/green/colored dot. If successful, this negates the bonus, and instead applies a -2 circumstance penalty to the shot. Does not work in rain, fog, smoke, snow, or similar conditions. Sound Suppressor: The normal Listen DC for gunfire is -10. With a suppressor, the DC is 5. Telescopic Sights: A properly aligned telescopic sight reduces range penalties to -1 per range increment, rather than -2.
