Querying weight limits of M10 factory strap

The new 75/1.25 is a heavy beast. This put me to wondering what the weight limits are for the factory M10 strap and even the body lugs? Would either fail under the weight of an M10, Viso 020, grip, thumb support, and the 75/1.25 with tripod foot? Does anyone have the specifications for the strap and body lugs?

I'm guessing, but I except that Leica have tested that...

The DR was quite a bit heavier and had lenses that were a lot heavier than that 75/1.25, yet it was meant to be used with the standard strap and R8 lugs. I don't think there is cause for worry.

I've been carrying around an M10 with 135 f/4 E46 version which is one of the heaviest non-Nocti M lenses (550g), and a 21mm external viewfinder. The standard M10 strap is not even breathing hard with that load.

 

However, in the interest of science, just for this question (and for grins) I just hooked my M10 through the loops of my mom's cast-iron fire-irons set (poker, shovel, bellows, stand, etc.) - which weighs in at 13.8 lbs/6.27 kg, and dead-lifted the entire thing (including M10 body, finder, 135 lens, and fire-irons) on ONE strap lug and the stock strap.

 

So total weight of around (?) 7.6 kg/16.7 lbs.

 

Now that is a dead lift of just the weight. Start swinging it around into doorways and such and you may get a momentarily higher force and possible torquing from a direction other than "up." But the strap and even just one lug seem well over-engineered for the purposes of carrying tha M10 and anything that can be rationally mounted on it.
