You cant have any sort of adjustable knobs so its not legal the way I read it.
P. Holsters with screws or knobs that extend past the outer face of the holster are allowed if the adjustment
screw(s) require a tool to change tension, the screws protrude less than 0.125” from the outer face of the
holster, and they meet all other holster requirements. Additionally, all tension screws anywhere on a holster
must require a tool for tension adjustment.
