Grenade Launcher

Dean Winchester owns a Grenade Launcher which he keeps in the trunk of The Impala.

The grenade launcher is first seen inside a weapons box in the trunk of the Impala in the Pilot episode. This version is a CAW 40mm airsoft grenade launcher. In subsequently appearances, it is replaced with a genuine DefTech 37mm launcher.

In The One You've Been Waiting For, Dean picks up the grenade launcher for the first time with the intent on using it against a group of Thules. Unfortunately, Sam tells him to leave it in the trunk, as they need to be stealthy. Once they enter the Thules' base of operation, they are immediately captured and disarmed, leading Dean to say "should've bought the grenade launcher."
