Thank you FastBolt. You are making the case that there is no real phenomenon, or perhaps more correctly, even if it does exist, it is wayyyy down the list of important things needed to get the job done. Yes, I see it is no biggie. Don't overthink it. Got it, thanks!
For the sake of argument, taken as a given purely for theoretical purposes,
say that there is a real phenomenon, how would one even account for it?
Barrel harmonics is a real thing in precision long range riflery. And it is obvious that very small deviations show up as a failure or a miss in the field, but I cannot wrap my head around applying that concept to a 2.75" barrel versus a 4.25" barrel at a range of 15 yards. On the other hand, I know that in musical instruments the tiniest adjustment can make all the difference because there are so many delicately interdependent parts.
When Paul Harrell was shooting the LCP, his groups were adequate but not impressive. "That is about the best I can ever do with these tiny pistols," he said. Perhaps 18DAI was surprised that his scores/groups were just as good with the little Chief as his other guns, not actually better. HR Funk was undeniably better with his CS9 but credited his long experience with that particular gun. "I have always shot this gun really well," he said.
Kind Regards!

Trying to conflate such things with different situations and equipment can take you down an unending series of rabbit holes.
Want to think about something odd? The barrel twist of a pistol barrel and how the barrel itself is affected by the passage of a bullet through the bore. The bullet turns within the barrel (rifling), but the barrel also turns around the bullet, to some degree.
I was told this by someone at S&W, during a call I'd made as an armorer, and the tech had some time to chew the fat about related issues. He explained that the barrel 'twisting', caused by the bullet acting upon the rifling, resulted in one side of the barrel chamber shoulders hitting down against the top of the frame harder than on the other. This was usually something that might be seen (if anyone noticed it at all) in some aluminum frames, meaning the markings caused by the chamber shoulders dropping against the top of the frame.
Naturally, whether it was a RH or LH twist would make a difference on which side of the barrel shoulders dropped harder.
