Mesh collision broken

So I made a gun mesh for a game I’m working on, but the collision of the mesh is causing the movement to break. If I walk in any direction the mesh’s collision causes the player to start floating around in a sporadic manner. Every other movement mechanic works fine. The thing is, I’ve tried just about everything I could think of to remove collision including turning collision preset to no collision, turning generate overlap events off, and a few other things I can’t remember. All of them didn’t work and tutorials didn’t help so I’m coming to the forum.

(I don’t know how quickly I’ll be able to answer by the way.)
