Gee David! Tell us what you think; but, don't stop unless you provide an alternate and your reasoning.
Kydex is an excellent material for a holster when used properly and it will not retain moisture like "animal skin" holsters. It won't lose its shape, securely retains the weapon and at an affordable price.
First of all, Fobus is NOT, repeat, is NOT kydex. It is a different sort of polymer.
That said, not all kydex holsters are created equal. Some suck, some are "good," while others are pretty damn nice.
Fobus sucks for a serious holster. Surely, you've seen the quick "disarm" by the role-player twisting the Fobus off the paddle. The new ones add a metal strip to prevent or at least slow down that action.
Evenso, the fobus holds the gun wrong. IE; it brings the butt in too close to the body for the wearer to obtain a good firing grip. If you come straight down on it, for a right hander, it'll point to the right once you get it out. Also, if you pull it straight up, the gun will engage the triggerguard indent even harder, making the draw herky-jerky at best.
What happens in my classes is that the wearer does what I have dubbed the "Leaning Tower of Pisa" draw. A right hander leans heavily to the left to obtain a proper firing grip. It takes time and requires a standing position.
Leather holsters can have this shortcoming as well. I recall watching gunsmith Richard Heinie do a "Leaning Tower of Pisa" draw from the holster HE designed and had executed in leather. I smoked him on that stage, as well as the match, my first shot always besting his. The funny/sad part was, he didnt' realize how hampered he was by using that holster. Then again, few people do.
The better holsters, such as made by KyTac (
