30 minutes or so into the episode, Benny is in the car with a pistol alongside him. Nyla asks him if he got a permit for the gun. The pistol is clearly an airsoft replica as it's marked Cal. 6mm BB, Made in China.
When the pistol in Benny's car is first shown, it is a Sig Sauer P229 AirSoft pistol with the safety orange barrel cap removed. The Cal. 6mm BB marking along with the safety warning and Made in China can clearly be seen on the bottom of the frame.
