Slide the index finger upward across the paddle while executing your natural draw and the retention mechanism within the triggerguard is instantly released. The releasing paddle has been located on the holster so that continuation of the draw naturally positions the index finger alongside the slide/frame, well above the trigger.
As with any new equipment, practicing to attain the proficiency that is possible with the CH holster is a reality that cannot be overlooked. This is especially critical if this, or any product, is to be employed in a tactical or self-defense situation.
Look for CH series holsters for the S&W M&P, Springfield XD, Beretta PX4 Storm, and Taurus PT 24/7 G1 in 2014.
