It’s an IWB holster, which is a very normal style. Nothing says it needs to be appendix carried, and it actually is referenced as designed mainly for side carry. I don’t see anything inherently more dangerous about it than other holsters, it just has an optics cut out.
I’m still unsure what accidents will cause a trigger guarded and thumb strap secured Glock to go off.
I think the argument being made is that IWB holsters are inherently more dangerous than OWB holsters. I understand your point, nothing should happen, however as we've seen with the sig p320 and a couple Taurus models, guns just go off sometimes. Accidents happen and adding one more degree of separation between the gun and your body isn't a terrible idea.
An IWB carried at the same position as an OWB has a barrel pointed the same direction. Both carried at appendix will be the same as both carried at 3-o-clock. The original comment (not you) has really clamped onto the gun-pointed-at-balls as if that is an insurmountable issue, when the holster’s manufacturer recommended it not to be carried that way.
Not sure what the difference of pant material being over or under makes for deflecting anything.
I know there's a video floating around of Massad Ayoob, a known fud, bemoaning iwb holsters. I personally use OWB because I'm a husky lad and don't feel like buying bigger pants. I think the holster you shared is neat, just not for me
Ayoob has done a lot, but yes sometimes his opinions should be regarded only as opinions. I haven’t seen what you’re talking about but I’ve seen him talk about other things where I was kind of pulling my hair out.
OWB is certainly viable if you’re willing to wear shirts to cover it. Comfort is a reasonable factor. I do think IWB limits the size of what is comfortable to carry. Even a Glock 19 I find too big for IWB for my own comfort. I have gone into carrying “pocket guns” IWB, and anything bigger OWB. “Pocket guns” IWB also eliminated having to size up pants for carry as much, because yes that’s annoying.
If you want to point a gun at your genitals, that's up to you.
If you're carrying it everywhere, you're going to bump it on things. You could accidentally discharge while drawing it or replacing it in your belt, especially if you're in a hurry.
There's a ton of obvious ways you can seriously injure yourself. But if you have to ask us about it, you've already rejected them and we can't help you.
As I said, not an inherent part of the design. It is recommended for a 1-3 carry, not appendix. I’m going to respond to the rest, but from the POV of carrying in a manufacturer recommended position.
bump on things
The trigger is covered by the holster. The Glock won’t bump out of the holster, mainly by gravity and extra secured by thumb strap. I’m unsure how it would go off while covered and secured
Drawing
Finger on the trigger during a draw is negligent rather than accidental. I’m not sure how any given holster design is more or less safe when the factor is somebody improperly grabbing the trigger way too early.
Replacing in belt, in a hurry
Not sure why this would be hurried. If the Glock needs to be removed, it can come off with the whole holster, so putting it back in the holster in a hurry can be entirely avoided.
