I've never held a gun that allowed any sort of natural grip if my arms are locked out; my shoulders are just about touching my ears.
I know some people, the kind who shoot tens of thousands of rounds a year, who believe that locking your elbows leads to joint problems, since the recoil is coming back through the joint, rather than the joint bending - which is what joints are for - to absorb the recoil.
I shot Weaver in my youth - the salient feature is not the bent weak-side elbow per se, but thrusting the weak-side shoulder forward, which results in a bent elbow - but quickly changed to "modern" isosceles, or "flexed" isosceles, as demonstrated by The Great One, above.
If the grip and stance are "neutral", the gun will track straight up and drop straight back down without having to fight it.
