I have been on a search for the perfect IWB holster (for me) and after lots of money spent and different options tried out, the DeSantis Pro Stealth takes the prize.
It's comfortable enough, although a little wider than some others, but the nylon construction makes it ideal for Florida weather. The holster covers great portion of the slide to protect it from sweat corrosion. The draw is smooth but with good retention (I'm still breaking it in though)
I love the built in extra mag pouch on the spine of the holster. Big plus for my POU.
My Kel-Tec PF9 disappears in my waist and I can wear this thing at 4 o'clock all day long :)
I'm including pics for you guys to check it out.
