If the PH wants to walk in front of me with an African carry, I have no issue. But neither he nor anyone else is going to walk behind me with that carry.
I shall simply note again. For safety reasons, any hunter attempting such a carry with a double on any guided upland hunt on this continent or Europe would be asked to correct his carry immediately, and should he persist, would be sent packing.
Indeed, I also can't imagine a guide tolerating such rifle handling on any big game hunt on this continent or Europe.
There is no such thing as a "bank vault" safety no matter what the gun cost. A loaded firearm is exactly that, and the muzzle should never cross anything but an intended target. It is hard to imagine a carry more likely to violate that basic safety rule than a firearm in African carry in a line of people.
Of course there is, in principle, not literally a bank vault, of course. The existence of a massive safety that blocks all possible modes of release is a fact. What you do with it is another mater.
Safeties exist because firearms are loaded, not because those who designed them believe they magically unloaded rifles.
Just to get it out there, I am a believer in the 4 rules, and believe, I hope correctly, that muzzle discipline is the greatest of these.
That said, let's not forget this is also a political mater. Which is to say there is a slide to nonsense ideas. Gun banners would like to make firearms inoperable while they wait for ultimate victory, and would like to impose disarming safety features on shooter. Decoder rings, and such. This has led to the religion around "my finger is my safety". I get it, preach it to the cheap seats. If you watch gun videos, the tactical guys are on and off their safeties like a squirrel on crack. Presumably for some reason. Those safeties probably don't hold a candle to the Mauser safety in their "bank vaultness" Do AR safeties block the trigger and the firing pin with convincingly machined parts? (I don't own one).
It would be interesting to see who makes the finals in the Darwin awards, people relying on finger control, or people with bank vault safeties, equally properly deployed. Of course, one can use both.
PS, I do maintenance on the brakes of my US and Japanese cars. If I had to bet my life on the brake mechanism, or the safety of "best" rifles, I would bet on the safeties, they are that well built.
PPS, I am not familiar with the decocker safeties on guns like the R8, but they seem a substantial step ahead of previous technology. I don't know if they are as bank vaulty, or have a lot of loose and stamped parts in them. But in principle those guns are unfireable when decocked with a round in the chamber. The problem for the PH is whether he knows those guns are on safe, given that they may be in the hands of profoundly untested people, the guns don't flag their condition.
PPPS, Pretending that well thought out safeties are not something to rely on, is probably not in our interest either.
PPPPS I agree that pointing a muzzle at a guy is unacceptable, and I do recall the few occasions when it has happened, with distaste. That said, try riding a bicycle in a world with drivers on their phones. Sometimes I have to pay up, when I didn't authorize the payment, just to enjoy the sports I like. We sure are lucky in hunting that one can normally work out such maters far more effectively.
