That's correct. I don't appendix carry, but it's certainly got it's place and has some strong points. I don't pocket carry in pants pockets, but it works very well in limited circumstances.
However that's not what's under discussion. Cavalry draw with a reverse cant prevents you from getting a firing grip, a fast presentation, and will make it difficult to consistently defeat the retention strap. Speed, consistency of draw, and surprise are consistently important in winning gunfights. Carrying a gun to defend yourself or others is literally deadly serious business. He's hampering himself, and that could cost him his life if he's called upon to actually use that gun. This isn't playing pretend at the range. This isn't comparing the width of the tie to the width of the lapel. This is something that could get him, or someone who emulates it, killed. If the hippy "as long as you're comfortable with it" crowd is offended, oh well.
The "at least he's carrying" tells me you haven't dealt with the aftermath of someone who decided to fight, and lost because he wasn't fast enough, his gun wasn't operation, he hit the bad guy but the bad guy hit him back, etc. That false confidence of the gun as a talisman leads to people thinking they can tackle something they can't. Then they pay for it. But at least they were carrying when they were raped, shot, stabbed, etc. Probably comfortable, too, right up until then.
This is a gun forum. Discussion of the pros and cons of carry positions is not out of the ordinary. You've yet to add any "pro" to his method of carry. You've criticized us and thrown your snarky "Welcome to INGO" remark in like we're insulting the guy personally. You called INGO out, I looked at your last page of recent posts, the irony was there.
If you'd like to actually discuss a valid reason to carry as the photo indicates as opposed to traditional IWB or OWB, appendix, or even crossdraw I'm all ears. Else you're just criticizing to criticize.
Ok, assuming were still talking about the pic in the OP, I've been thinking of some "pros" of the carry method. You, of course know, that it used to e standard practice (before widespread use of BP vest) to "blade" yourself when encountering a potential threat. I think in the method that individual is carrying, it may be beneficial, and even superior to standard carry when one is blading themselves towards a threat (this would assume concealed carry-like with a jacket). If a potential threat approaches you, you can blade yourself to them and raise both arms to keep a reactionary gap. If you have to present your firearm, again from the bladed position, you simply lower you hand, rather than reaching back, and to the far side of the body. I'd have to see it in action, but my thinking is that you could engage the threat quicker. Is that bad logic?
