Nonsense. Try playing a guitar for the first time. It'll hurt your fingertips. Only with PRACTICE does it become easier as your fingertips toughen and callouses form. Same concept. Like I said, and this has been proven by folks who shooting heavy recoiling sixguns exclusively, recoil tolerance is made, not born. Once made it has to be maintained or it will be lost. Yes, very simple concept.
Saying training is necessary to control recoil is one thing. To make an irrational generalization that those who feel pain from it is lazy is a different thing.
Human will can conquer many things, but one thing it cannot defy is laws of physics. There is a price. Such as damaged shoulders of shotgun instructors. Such as Jerry Miculek's damaged thumb nerve(he states so in his education video). Any reasonable person should weigh that price against shooting a high recoil pistol.
You don't get something for nothng. Many shooters learned the hard way, thinking "Ooo, I shot this a while and now I can handle this and feel no pain anymore." just to realize years down the road that they messed up their hand beyond repair and they cannot enjoy shooting as much as they want do any more.
It's just like countless infantryman who served who "got used to" carrying 100 lb+ weight and marching 20~30 miles, and realize they are headed for 100% disability and end up strolling around in a hov-e-round. I realized "getting used to" really isn't, and acted accordingly. Which is the reason I was able to get out of the infantry without major disability.
"What do you get in return?" is a valid and necessary question, especially when there are plenty of options avaiable that does not involve disability and loss of combat efficiency.
I hate shooting my 642. Even hate it even more to shoot 38 +P. Can I shoot it? Of course I can.
But, why? I can simply replace that with a steel J-frame and get higher efficiency wihtout the pain. I can shoot an even more powerful 9mm from P290 which is even more compact. Why should I spend my own time and money to subject myself to pain when I get nothing better in return?
There is a reason why respected combat experts stick with guns with recoil that ranges from 9mm to 45ACP. It's not as if people like Paul Howe, Bill Rogers do not shoot a 10mm out of their full size service gun or advocate carrying a 357 Magnum full power load in a airweight for combat training becaue they are "lazy" or "fear getting embarrased in front of a crowd."
