This is probably real simple and I'm just making it harder on myself.
So far I've mostly used comp-tac holsters. All of that comes with the hangers and everything for belt or even tuck options. I just use the belt hanger with drop offset.
However, I recently acquired (secondhand) what I believe is a RHT tactical holster. It has a 3 hole pattern drilled in it (like the predator's targeting reticle) and no hanger. There's a million hanger options out there and I just want to make sure I get the right thing.
Some questions:
Do all comp holsters have the same 3 hole triangle pattern in them so that pretty much any hanger will work?
Are all the hangers more about belt attachment, drop, and offset because they will attach to any holster with that 3 hole pattern?
If there are different holster hole patterns, how do I know which is compatible with the 3 hole pattern? Is there a name for it?
And, finally, for a (maybe) RHT holster what would you recommend for a hanger? I'm looking for something with some drop but don't care too much about offset.
