• The attribute -34% clip size is missing.

• The attribute On Hit: Victim loses up to 10% Medigun charge has spelled Medi Gun incorrectly.

• The shots fired by the weapon are fired slightly below the reticule.

• Rarely, after a moment of not firing, the Engineer will automatically reload the weapon's clip, regardless of the player's auto-reload setting.

• While holding down the primary fire button, if you hold down the secondary fire button simultaneously the Pomson will be placed into a still loop of the reloading animation without actually reloading the weapon until both buttons have been released.

• For about the first 128 Hammer Units of their flight, the weapon's small energy beam projectiles get intercepted, deviating from the expected projectile-based weapon friendly fire rule.

Also needs particle remake, since you can't tell If pomson particle is a crit or not.
