Does anybody else share my opinion that a proper functioning auto pistol will work no matter who or what is pulling the trigger? The "limp wristing" story is BS to cover up a sub standard gun/ammo problem.
Well, I have a number of armorer manuals out at the bench, from a few of the major gun makers who do a lot of LE/Gov business, and I can offer that "grip problems" are listed as probable causes of some different feeding & functioning problems in virtually of them (I can think of at the moment) ... and that includes pistols made with metal frames by some companies.
I prefer to call it a "grip stability" issue, myself, instead of "limp wristing". It can involve grip firmness, technique and/or an unlocked/broken wrist. It can also vary from one individual to the next.
I've watched it occur more often than I'd care to see over the 20-plus years that I've worked as a firearms instructor (and much of that as an armorer).
Sure, it can be more commonly observed when a lot of folks are shooting some of the plastic-framed guns, but I've certainly seen it happen among enough shooters who were using good quality metal-framed guns. (Even good quality & properly maintained 1911's

).
Some folks can seemingly experience it regardless of how hard they try
not to have it happen, and then some folks can't seem to
make it happen, no matter how hard they try to do it.
I've seen it repeatedly occur with a plastic .45 for one shooter (T&E gun), but nobody else had any problems using the same gun and the same ammo, before and afterward, that day and then spread out over many weeks. That particular shooter had no such problems shooting an issued 9mm, or any of the other T&E guns chambered in .40 & .45, both plastic & metal framed guns.
It can be addressed as a grip problem, although then some ammo may come along that's produced on the lower end of the normal power range (or it's under-powered), and then we're back to it being an ammo problem.
Day in & day out? More often it's a shooter grip technique & stability issue.
