Has a significantly tighter hip fire spread
Has a Faster Fire rate
Has a further one shot kill range
Deals more damage per shot.
Has a fully automatic capability as a last ditch attempt of surviving by emptying a complete magasine in rapid succession although this reduces damage and increases Hip spread.
Marshall pros Vs Jackal.
Can mount a silencer.
Has a larger default magasine capacity of 10 rounds instead of the jackals 6 +1.
Has a healthy total ammo count of 40 shells compared to the jackals 30.
The main Reason for choosing a Pump action normally is for those one shot kills and great accuracy, Although the Marshall suffers in both of these categories and the only reasons you would choose the Marshall are for its large total ammo count, Silencer or just straight up humiliation.
