This whole thing really does go to show just how -silly- it is for people to say that if you have sweat on your hands it might prevent you from gripping the gun well enough for function. I mean...lol
Having a wet (and/or cold) hand can, however, seem to prevent some folks from
acquiring a proper initial grip on their gun during drawing & presentation, which can complicate maintaining an adequate grip during recoil & torquing.
Your 2 videos show an apparent intentional reduction in
grip firmness, but your shooting hand is still nicely
aligned with your wrist & forearm.
This is an important consideration than many folks miss when trying to diagnose a grip stability/technique problem that results in a feeding stoppage and/or ejection issue.
I've never liked the term or description "limp-wristing" when it comes to semiauto pistol functioning issues. The looseness or lack of firmness of the actual grip is
only a part of the potential problem with some shooters. The angle of the wrist/forearm relative to the gun hand is also very important.
When a shooter "breaks" their wrist behind the shooting hand, allowing their wrist to acquire an angle in one or more directions (or planes), it can substantially reduce the support of the frame ... independent of the grip's firmness. Two different influences that can be acting on the gun hand's support during the recoil cycle.
I've seen some shooters "break" their wrist inward, moving the gun more toward their center-line, while raising or lowering the gun relative to their elbow/forearm, flexing their wrists ... and at the same time they may also let the gun come closer to their torso or loose clothing (think car coat, bulky sweatshirt, etc). They may be gripping the gun with their fist firmly, but "breaking" the angle of their wrist may introduce 2 disadvantages.
First, it reduces the support of their forearm (bones) being aligned directly behind their gun hand. The actual grip may be less-than-ideal, but the
support of the wrist/forearm may mitigate that "loosened" grip influence.
Secondly, it shortens the distance between their gun hand and their clothing (or torso), which may result in a "torquing" gun's slide to have a weakened (velocity) & shorter slide run ... and
also risk bumping up against their clothing (or body) just enough to rob slide travel ... inducing an ejection problem or feeding stoppage. This can be a grip-technique-relative-to-clothing-and-body-indexing issue.
Then, there's the folks who can somehow manage to induce a grip stability stoppage while shooting 1-handed/point-shoulder, or even 2-handed, up and away from their clothing/torso because they unintentionally
reduce the support of their wrist/forearm behind the gun hand.
Then there's the folks who
can't seem to induce an intentional grip stability functioning issue ... unless they come across a low-powered round of ammo.
Trying to fix such shooter-induced issues can be complicated by not properly diagnosing what's actually happening. Sometimes it's not just one influence at work.
FWIW, over the years of watching grip stability issues occur, it's seemed that more often than not, it's involved some lack of sufficient grip, but also someone unintentionally "breaking" the angle of their wrist/forearm behind that less-than-ideal grip.
Now, introducing shooter movement, or reacting to the presence of a barrier/barricade, can complicate shooter grip technique & stability in even
more interesting ways.
