Don't have one but have several that look like it that are not particularly comfortable. Look at the StealthGear Onyx before you buy. It is my favorite for my Shield. Wear it 8-10 hours/day.

Looks like a nice holster at a good price..Does anyone have first hand experience with a Cover 6 Gear IWB holster with the adjustable cant? A friend has on on his Berreta and I am considering on for my shield.
Thanks.
