Hi. I usually choose the AK-47 assault rifle because it's pretty versatile. This weapon has great accuracy and power, which makes it the perfect choice for most situations in the game. It's also cheap enough that it allows me to save money on more expensive items like body armor or grenades. You can find even more weapons here https://xplay.gg/store .
I, on the other hand, prefer to use pistols. I find they are more maneuverable and faster, which helps me survive in fast situations. I often choose the Desert Eagle because it has tremendous power and killing power, but requires skill and accuracy in shooting. I also usually choose a second gun, such as a Glock-18 or P250, so that I have a more powerful weapon at close range.
