XDefiant features its fair share of customization options, from the various Factions players can choose from, to the weapons they can equip to their loadouts. There is a large roster of weapons players can opt for, with some of the more favorable options among the playerbase being those found within the Submachine Gun category. Though the MP7 is undoubtedly the most popular SMG available, the Vector .45 ACP is definitely a viable option.
