You have to attach your gun to a socket. To do this either parent it to your mesh’s right hand and position it manually inside your blueprint or make a socket on the right hand inside the skeleton and position it. You can also add a preview mesh on it. If the hand bone is rotated in such a way that the gun doesn’t face directly forward when patented you can eathet rotate it to face approximately straight forward or you can add a attach to component inside your construction script and parent your gun to the right hand bone or the socket you created and use “keep world” for the rotation.
