So most people use the method where they wait for the gun to come out and then switch to their betties and hold square. For me an easier way is to put your gun in the pack a punch, Immediately pull out your betties while the gun is still in there(you may have to press the right button more than once),and then hold square until the gun comes out and when it does you should grab it and trade in your betties. I like this method better because I have screwed up doing the other method and this way you really can't screw up. Found by me a long time ago but I decided to post it now because no one else has.
