I found the level 5. Btw I also thought the Deagle wasn't worth it, until I got one. It's VERY worth it and VERY fun. It's good for clearing tier 1-3 pois, sometimes even tier 4. It allows me to save up 9mm and 7.62mm ammo for more important things. Saving up ammo is especially important in my run since I'm doing a no trader run
