Well, what if you dress like an adult, and don't want to look like a slob, with your shirt un tucked? You still need a top layer; a hoodie was an example. I don't speak or dress Walmart. After they hit you, than you could consider it a possibility of great bodily harm. Have you ever seen "the knockout game"? What if there were some morons that started a "gut punch" game. Maybe your Spidey sense would alert you in advance. Let's say you are walking from the supermarket building to your car, and have bags in one hand, and your young daughter's hand in the other, because it's a parking lot, and some jabroni in between cars, jumps out and punches you in the bread basket? You're so fast, and have 100% awareness, that when your daughter is asking you if you can stop for ice cream on the way home, and you look down and smile and answer her, that you can account for every person in the parking lot? Must be nice to be a superhero and know when and where any possibility of danger could come from. Imagine the same scenario, only the attacker jumps out with a bat and swings at your torso? Assuming you didn't already lose consciousness, are you going to be able to decide quickly, to pull or secure your kid? Appendix carry holsters are like Hallmark holidays, just another way to make money. Just about as stupid as the chest carry harness holster, that as a civilian, has no practicality, in day to day life. Or the people that spent the money on those specialized concealed carry t-shirts with built in gun pocket. I'm going to design an athletic supporter holster, so people like you can kill two birds with one stone; have a stupid place to carry a gun, and with the barrel down one leg, look like you're not hung like a hamster.It's good to see that your lack of knowledge and experience with the method doesn't hold you back from sharing your opinion.
AIWB works fine with any kind of untucked shirt. Sweaters, t-shirts, button downs -- it doesn't matter. It's not restricted to hoodies (I don't even own any). It works with any style of dress that you can use with any other IWB or OWB holster set up.
As far as physical damage, if someone can hit me hard enough to rupture an organ, then that's more than enough threat of deadly bodily harm. If anything, having a gun/holster is going to disperse the force of the blow rather than leave it concentrated on the attacker's fist, so it's actually more likely to produce less harm than more. (Whether it's at 1 o'clock, 4 o'clock, or 5 o'clock. It's this little thing called "physics" and force dynamics.)
