The core assumption here is that it's fixed time to handle a gun, not affected by person agility or other stats (usually mean as the mechanical action of the gun itself), thus the number of shots a gun can make per turn never change regardless of who uses it. It can be disputed how accurate and applicable such assumption is, but it's quite popular (as often aid in game balance besides other things) and is used by original JA, and never reversed.

; Increased speed by percentage when firing 
GRENADE_LAUNCHERS_FIRE_AP_REDUCTION = 20

; Percentage APs reduction to fire pistols and revolvers

; reflex sights, this gives them at least some compensation
FIRING_SPEED_BONUS_PISTOLS = 15

The only way someone can physically shoot a gun faster is by aiming it faster, and it's already covered by reduced aim clicks needed for full aim in NCTH, so it's simply gun magic :-)
