A squib load, also known as a squib round, pop and no kick, or just a squib, is a type of firearm malfunction in which the fired projectile does not have enough power behind it to exit the barrel. This can happen for several reasons, such as insufficient or no powder load, a failure of the primer to ignite the powder, or attempting to fire a bullet that is slightly too large for the barrel. Squib loads are possible in all firearms and can be caused by negligence in the powder loading process. Squib loads are known to occur even in reputable factory brands.

Signs of a squib include failure of the action to cycle, a muted bang, and no recoil. If a squib load occurs, it is important to stop firing immediately and unload the gun. Firing another round before removing the bullet can cause the gun to blow up. To prevent squib loads, it is important to use quality ammunition and to check for powder and primer issues. Squib loads are rare in factory ammunition, but they can still happen.
