I bought the model #17 - IWB Interchangeable.
It was very well made, and I had it constructed with a "sweat guard" also. But my complaints were:
* Retention was too tight. No adjustment screw (I think it was an option that I didn't take), and even though I wedged the gun in the holster with a sock wrapped around it for 3 days straight, it never loosened up enough. Couldn't draw worth a crap. I'd hike my pants up to my chin every time I tried to get the gun out. And tightening my belt only made things worse.
* Belt loop just didn't do it for me. I got it with the leather slotted snap loop:
This loop just didn't hold the holster securely enough for my tastes. Granted, part of this problem was the extreme retention of the holster; when drawing, the holster would move all over the place, and I'd give myself a wedgie trying to get the gun out. Might have worked better if the retention wasn't like super glue.
* Belt loop attachment scratched my gun. Yep. Since the belt loop is adjustable/cantable, the screws that hold it in place can be loosened & retightened at the desired position. When fully tightened, these screws protruded into the top of the holster, scratching the slide whenever I'd draw & re-holster. Loosening the screws made the belt loop slide out of position on the holster. Trimming the screws down would have solved the issue, but I was already unhappy enough, so I didn't even try.
Again, the company was good, and the holster seemed well made. I think the extreme retention was a big part of all my issues. I think I quickly figured out that I like Kydex better than leather, and I'm very happy with my CompTac now. I was very pleaed when Fist took back the holster for a full refund.
They have a LOT of different styles of holster - kydex included - and I wouldn't hesitate to try something else from Fist in the future. The #17 just didn't do what I wanted it to do.
