I recommend grip exercises and plenty of practice if you are going to African carry.
Personally I don't understand the Africa carry. It is a walking gun safety violation. Have yet to see anyone NOT flag someone. To each their own, it is just something I'm not willing to compromise on.
Never point a gun at anything you are not willing to destroy and take full responsibility. Treat every gun as it is loaded. As far as I know, that holds true not matter where in the world you are or what activities you are doing.
Maybe I am just one of those guys. If that is the case I can live with that better than explaining an accident. My .02 which is worth what you paid for it.
