Scouse

It's like cooking... take one Glock OTB "Combat Holster" and chop chunks off it! The major area of reduction being at the top portion of the holster, at the front.

Your draw portion of the holster is reduced by 7/8" of an inch. So the muzzle clears the plastic 7/8s of an inch sooner, that is about 1/3 less, 33% is a big reduction. This reduction also allows you to feel the extractor with your trigger finger tip, you know there is a round in the chamber with the pistol securely holstered.

Even if all you do is cut the slot pins to fit your belt (in my case 1.5" belt) a Wilderness Instructor belt, the frequent flier model, no metal, it is a close fitting to the body holster, that weighs nothing.

Mine is used for every day carry, for my Glock 19 (ain't Florida Great?) and IDPA/IPSC.
