How to create a collision for Guns?

HI All

I’m having collision problem in my project. In my project the weapon mesh is not colliding with the actors. Even we tried adding collider to the weapons in the blueprints and many other ways also, but still the weapon mesh is going inside the walls, pillars etc. on the map. I wanted the weapon mesh to stop after hitting the wall it should not overlap with the walls, pillars etc. We added blocking volumes to the walls and pillars in the map but still we are facing this issue. Please help us for solving this issue.

Thanks&Regards
Programmer.
