I haven’t read the entire thread but will start here.
Yes there are leather AIWB specific options they however, are very niche and pricey.
JRC made the “Watson Special”, which was a collaboration with Joe Watson of Watson knives and another holster which I can’t recall the name of.
Palmetto leather and TT Gunleatherare making some now too.
If you want the best though it is made by John Ralston of 5 Shot leather. It is named the “SME”, after its codesigner who was/is a federal agent that was looking for a leather AIWB holster that concealed as well as kydex. John’s work comes with a serious wait and price tag and he is not the best to work with (I’ve got a decent amount of holster made by him).
Someone asked what makes a holster an AIWB holster; it typically has some sort of “wing”, built in to help rotate the grip of the gun inwards to aid in concealment. In the case of the SME is also has some reverse cant to position the grip parallel with the belt line.
Here is one of mine, 7 years old and still working great. The other is a JRC I sold off. I’ll add some details in another post.View attachment 1800586View attachment 1800583
Great post! Those are both very good looking leather holsters. Is the wing on the black one leather? What does the other side look like?
