After reading all the positive reviews, I pulled the trigger (just kidding) and purchased the Blacks Ops Pro from Rocky at Pure Kustom Holsters. Dealing with Rocky throughout the process from ordering to receiving the holster was a pleasure, Rocky is a consummate professional.
I selected the Blacks Ops Pro because of its versatile design. It can be worn outside the waistband or inside the waistband with multi position adjustment for height and cant and is tuckable.
I have been wearing the Black Ops Pro every day for two weeks and I can tell you in addition to being a work of art it is an extremely comfortable holster and sometimes forget I have it on. After drawing reholstering is a snap as the holster does not collapse. It is one hell of a well-made holster.
I would not hesitate to order my next holster from Rocky.
