Supertuck style holsters work OK if you cut the leather enough to get a good firing grip on the gun during the draw...you'll find you'll need to take away a LOT of leather to get to that point. Comfort is great, but if you can't get your hand on the gun and get it out of the holster in a hurry then what's the point? What is more important, a proper firing grip on the gun or comfort?
Some holsters do both, most do not. Generally speaking for IWB holsters the most comfortable options will also be the least accessible. Which is why I run OWB...plenty of comfortable options that allow for a good grip on the gun while drawing.
Plus paying $80 for the Supertuck is a JOKE. Should cost half as much...I know many others make the same thing for half the price, or less. At least with something like the MTAC it looks refined, like it actually costs $80. The Supertuck looks like something I can make at home on a boring Saturday night.
