I found this guy's site while doing an Internet search, so I have no more details than what is presented here.

D. Gallagher is making these holsters on a custom-basis, i.e. each holster is made to customer specs. The following models are available:

The "A.D.S.. Scabbard"

This holster has belt slots front and rear and hold the weapon very close to the body. A very concealable rig. Available in black, brown or tan.

"JEFFEE"

A belt slot and tunnel loop design that is very secure and concealable; however, it does not hug the body as tightly as the "A.D.S. Scabbard". It's a hair faster for some folks. Available in black, brown or tan.

"TEXICAN" IWB

This is a safe and secure new version of the very popular Mexican carry which is, "stuff it in the waist band and hope it's there when you need it!". The Texican is very secure, stable and concealable. The belt straps are placed front and rear of the handgun, not at the thickest point such as over the slide or cylinder. This rig also features a unique hidden hook and loop system that adjusts to fit various belt widths. Available in black, brown or tan.

"Tuckable"

The Tuckable was developed for the individual that needs to be armed in an environment where a jacket, vest or other concealing apparel is inappropriate or would call undue attention to them. The "Tuckable" is variation of the "Texican" inside the waistband holster. The belt straps are placed front and rear of the handgun, not at the thickest point such as over the slide or cylinder. This rig also features a unique hidden hook and loop system that adjusts to fit various belt widths. The straps fasten to an additional leather panel which is fastened to the bottom of the holster body. This allows the shirt tail to tuck neatly between that panel and the holster. The shirt tail covers the holster and conceals the weapon. This rig is better suited for compact to medium-frame pistols and revolvers (i.e. J-frame S&W, Para-Ordinance P10, Colt Commander, etc.). Body size/type is another consideration. Each holster is gun specific, custom-made to your preferred angle.

For some of these models, an extension of the rear part of the holster can be ordered, which covers the hammer area of the gun, in order to protect your skin. This feature (named... "skin saver") can be ordered at no extra charge. Of course Gallagher is also offering a double mag pouch to compliment his holsters.
