The Turboprop retention knob Is the fastest and most positive way to adjust retention. With its 3 large propellers, it allows for fast and tactile adjustments on the fly. The added circumference means you aren’t turning and turning and turning, just to adjust your holster. These are especially great for 3 gunners as it allows you to tune your holster from stage to stage. Have a stage where you will be drawing right off the buzzer? Loosening the knob will give you a faster draw. Have a stage with a lot of sprinting? Simply give it a few turns tighter for extra assurance. No tools necessary.
Turbo prop kit works in any holster with adjustable retention, and included the prop, screw, and a standoff spacer to give it a little added height,if necessary.
