The Lawgiver unlocks at level 24 and appears as the SIG Sauer P226 (Signature .40 Pistol). This is a very unique firearm boasting pretty average stats for a handgun its size, but the juicy stuff is hidden within its various ammunition types taken from the movie. Those ammunition types include:
Spoiler!
Armor-Piercing | High-power piercing ammunition that goes through Shield units and heavy enemy armor.
(+15 damage, -8 accuracy, +8 stability, -10 total ammo)
Rapid Fire | Converts the Lawgiver into a high damage, fast-firing handgun at the cost of accuracy and stability.
(+5 damage, -8 accuracy, -8 stability)
High Ex | High-explosive shrapnel ammunition that explodes on impact.
(-3 damage, -8 accuracy, -14 total ammo)
Incendiary | Ammunition that explodes into 12 pellets of fiery shrapnel, dealing fire damage to enemies over time.
(-9 damage, -4 accuracy, -10 total ammo)
Hotshot | A more concentrated version of the incendiary ammunition, firing only 1 straight pellet that sets enemies ablaze. Has a lesser damage and total ammo penalty than its counterpart.
(-6 damage, -4 accuracy, -4 total ammo)
Stun | A poisoned bullet that stuns and poisons enemies on hit.
(-4 damage, +4 accuracy, -34 total ammo)
