Mega-Fit Holster utilizes the classic Index finger unlocking way to release your handgun, giving you simple and more reliable access. We lower the Thumb-Index web incision for red dot and elevate the Front Sight position for wider compatibility with the foresight-refitted or original full-size and compact semi-automatic pistols. It is also easy to adjust tension by loosening or tightening the four front screws to reach the perfect fit.
