The issue is that the name callers have no interest in contributing, it's just an opportunity to show how smart they are because they assume the carrier is an easy target for criticism.
Goes to a lot of carry methods - right now the internet standard seems to be "IWB or don't get off the porch." How nice, it has nothing to do with reality. If you need to deep carry, IWB will get you fired at your job if their is policy against any carry at all. As adults, we should all reserve the right to make our own decision about our safety, weighing all the risks, including unemployment.
Nobody is much defending the holster or method - but again, in the reality of life, all the forms of carry exist because somebody found that was a successful method for them at that time. Taking one picture out of the context of the event, it's easy to criticize - it's like a cop finding you next to a shooting victim with the perp's gun laying next to them. Oops, you will be in handcuffs until it's sorted out. Hopefully circumstances don't work against you, but it has happened, an innocent person serves time.
That view of life as being uncertain isn't demonstrated by the "dumb cluck" view. From that perspective, it's black and white, judged guilty by one fact, and condemned. Sounds like that is the way someone has been treated in the past - no consideration, no mercy. Adopting the attitude may not be the best thing to do. Playing locker room measuring contest on the internet, however, is the standard juvenile game on a lot of forums that lack adult perspective and experience.
So, should we all give up shoulder holsters never to return? Au contraire, it's the method used by a lot of people who need to deep carry with high demands about clothing and uniform wear. Thunderwear is another answer, highly derided on the internet, works well for those who can't print at their job or they lose it. Again, the black and white "I'm right and the world is wrong" attitude is too restrictive for reality. It's just reacting to how they were treated or posturing for social standing. "I sure told those dweebs."
Nobody is praising this guys carry - but I did remark that LEO's have used SOB carry, with two .38's in a double holster. Are two gun shooters currently a new target of derision, yeah, it's a recent post on a web site. Do you give a dumb cluck when you are armed with a revolver and need the 7th, 8th, and 9th round? It's called a NY reload for a reason in it's day.
What happens when you fall flat on your back, could you be injured, can it happen? Sure. When's the last time you did that? The average adult would have to be caught very unaware. We would attempt to regain our balance, and if you train in retention techniques properly, would you not try to fall in a manner to allow you to either access the firearm or prevent it entirely? Yes, it does go to a gun grab being a difficult situation, but with SOB in a confrontation, it's also a lot more concealed. Let's not forget that stand off is all part of training, too.
For every black and white "That's stupid and wrong!" there are circumstances where it works. What some "trainers" lack is experience and perspective about it, and trying to apply LEO or Range Rules to the difficult issue of daily carry. It might be something that appears to support the rules of safety, but it's not always applicable on the street. It's like saying "No carry into a Post Office." Yeah, that's the letter of the law, but it happens. Adults make their own choices, it's not about being a criminal, it's about not being the problem to begin with. It's what martial arts masters know - you can break the rules, it's experience and judgment that tells you when.
If someone feels prompted to take up an analysis point by point, they are missing the message. There are better ways to do things, sometimes you just pass by. You are not the sensei master to the public at large, and you are not an authority on all things in life. Trying to demonstrate it on a forum is the #1 "poker tell" you have a lot more to learn. One of those lessons is that sometimes you have to let others just make mistakes. It is, after all, why we are a nation - no other living person is your master, you need to learn and assess what is right in life and make your own decisions. While ethics and morals can and are black and white, methods of carry are far from it, and blanket condemnation isn't an example so much of expertise but a lack of it.
Like children, they eventually will grow up and you won't have to tie their shoelaces any more.
