A Burst pistol to make it more "lore accurate " and to add more variety would be the perfect fit, and it makes the sub regiment more exciting as it would be the only non-naval regiment with them, and to add onto the point that no one uses pistols its extremly common to switch to the pistol in the heat of battle as pressing a quick switch button is faster then reloading!An E-11 can finish off the enemy just as quick after firing an entire grenade at it. What’s your point?
