This gun is so EASILY spotted, It's blatantly a joke to use. The red silencer is massive, and just the gun would be better off using a CSS USP skin.
I think the point in the Malfunction Pistol is that you shoot it into a group of people from a distance, and they all get distracted by the random shooting, diverting the attention away from you. I think with a more discrete model, this would be too OP. Get's a -1 from me.
