Acquiring the JAK Gunslinger in Warzone and MW3 will be challenging this time, as the Season 4 Week 7 challenges are more difficult than what previous such tasks involved. For instance, many of the MW3 Multiplayer and MW3 Zombies objectives require the use of handguns.

To complete these challenges, it is recommended to use the WSP Stinger, as it functions like an SMG. It also has a high TTK and a high rate of fire, which are great for close-range combat. This weapon can help you complete the handgun challenges more quickly.

For MW3 Zombies, the TYR Akimbo is the best option despite its recent nerf since it is still more effective than other choices.

Most of the Warzone Week 7 challenges are also tough, as they require you to gather kills in specific regions. There are no other criteria, so you can use any weapon or method to eliminate enemies in WZ.
