Why mess with the design of your pistol? If you want SAO, then get into SAO-designed guns.
You sound like someone who is going to tinker with their gun to the point that it stops functioning reliably. This might be fine with an car, but if this is going to be a self-defense weapon, you are playing with your own life if you mess with reliability.
If this is not your primary, then go ahead, otherwise, leave it alone.
