First Person Gun Collision in PIE but not Mobile?

[TheWarlord25]

My gun, not custom, just regular UT weapon, collides while I preview in PIE but goes through walls when I view in Mobile. Any ideas why that would be?

I made the collision cylinder really big and that fixed it. Sort of strange way of doing it though, now I need wide paths ...the collision cylinder is quite large to make the weapon stop clipping though walls. I don't understand what the difference is between running in PIE and in Mobile.

Warm Gun has the same issue. What they did to solve it was, let the guns clip through walls. But when the projectile comes out, it's actually coming from the player's head.

Doing this fixed another issue where the aim was little off when firing from a distance, if it had come from the gun's barrel.
