Part of my job is being a gunsmith.
Another part, firearms (CCW) training.
The third part, custom Kydex holsters.
Concealed carry holsters have to fit the person.
Otherwise, you’re not going to carry the gun or it’s so uncomfortable that you don’t want to.
I got into holster making, because ofter 25 years of carrying guns, I had boxes of holsters that failed.
Either they weren’t as comfortable as advertised, didn’t fit the gun well, or some other malady.
So, I started making my own.
Now I build them for other people, fitting them to the person as well as the gun.
Shoulder injury prevents you from drawing a certain way, it can be accommodated.
Clothing issues? Can be designed and built around.
