I'm thinking of getting this new Kydex/Concealex IWB holster which is similar to the Mitch Rosen "Workman." I plan to use it for my S&W 442 J-frame. It is designed to allow the shirtail to be tucked in between the belt and the gun, covering everything but the belt loop.
I tried the Galco version in a store once and literally could not draw the handgun, due to a combination of the depth of the holster, the tight fit and the added resistance of the belt.
If anyone has tried the Blade-Tech, I would appreciate hearing how it works.
