As a "fer instance" he thought that each side of your brain could do one thing at a time under stress; so the obvious thing to do under stress was look at the threat with one side and kill the threat with the other side.
Anyhoo, he was of the opinion that the natural position of the human hand under stress was clenched into a fist. Based on this. he opined that the problem wasn't pulling the trigger, but rather relaxing your trigger finger out of the natural clenched fist enough to allow you to re-pull said trigger.
The solution? Pull the trigger, and keep the trigger pulled back through recoil, keep it pulled back until you reacquired the threat, then release your index finger and immediately pull it back. Rinse and repeat until the threat was gone, then relax your finger, remove it from the trigger-guard, safe your weapon and holster it.
When I got to the Panhandle Regional Law Enforcement Academy in the early '90's, Ken Ferrin and Mike Dunlap taught a similar method of shooting, called IIRC, "Trigger Reset". In this, we were taught on the first shot to pull the trigger until the pistol fired, then relax our trigger finger enough (about an eighth of an inch on the S&W 5900 series pistols we were training with) for the trigger to reset, then pull to the rear again.
When taught correctly, this is a fast and accurate way to shoot; but it can create a bit of a hullabaloo from newbie range-masters who see me transitioning to my second or third target with the trigger clamped all the way back*.
Good, bad or indifferent, under stress I default to this. Once the shooting starts, my trigger stays clamped to the rear more often than it's released. I do this with my pistol, with an AR15‡, and with my Mossberg.
Yes, under stress, I pull the trigger, work the pump, release the trigger, pull the trigger, work the pump, so-on and so forth.
I mention this, because by way of Caleb over at Gun Nuts Media we discover that this decades-old habit of mine renders the new Kel-Tec shotgun useless to me under stress.
I'm trying to like Kel-Tec's newest stuff -- really, I am -- but the last two of their guns I've played with have been problematical.
Oleg Volk brought his PMR-30 and his RFB to Blogarado, and I wasn't impressed by either one.
The first time I fired the PMR-30 -- and, granted, several other people had been playing with it before I got my paws on it -- it was pulling the rims loose from the case walls and failing to feed. I fired a couple of rounds through it and passed it off.
Later that day, Farmdad handed it to me after he had dunked it in CLP, and it went through a magazine fairly well -- only had to tap it into battery once -- but to my mind a pistol shouldn't have lube literally dripping out of it to get it to work.
The RFB was worse. Oh, it fired like a champ and ran everything we put into it ... but every case it chucked out had one of the most beautiful examples of primer wipe I have ever seen. To the point that OldNFO pulled the trigger once, looked at the case and then refused to shoot it again.
Vine, Farmdad, and I dinked around with that rifle for a while, trying to isolate the cause of the primer wipe, but only managed to launch the gas regulator knob across the Colorado high desert.
I understand that the Kel-Tecs that Oleg brought were early models -- if not prototypes -- but between the PMR-30 and RFB I've personally handled, and the news about the trigger
... folks, I've got to give the new Kel-Tec stuff a thumbs down.
*No, I don't move with the trigger held back, unless I'm shooting as I move.
‡No, auto-fire isn't a problem. Unless the weapon is belt-fed, crew-served and/or involves an electric motor, auto-fire is a fantastic way to convert money into noise, and is significantly less-efficient than rapid single-fire at punting critters in front of the Pearly Gates.
