I have had one for a year+, and I love it. It also makes a good concealment holster. I haven't used it in competitions as I have not competed yet. I usually carry with an IWB holster, but when its a belt slide, the practical is it.
I've got one and it works well for me till I can afford a race rig.
It has a tension screw so you can adjust it, I find it works well in my competitions now....I generally carry IWB or in a pack. For some reason it really feels like the gun protrudes when I'm carrying with my Wilson.
