I have. Have you? Remember the part where you drop the rifle to it's sling after firing to be able to control the attacker's weapon hand if you need to? This was taught as part of a transition to handgun. I can do that while still firing with a handgun. If I had a rifle and a handgun, I could do it while transitioning as was taught, but this scenario was one or the other, not both. Your 3ft long club should be attached to you by a sling, leaving you less mobility with it than you'd figure.
