I received my 2.5 awhile ago, and love it. I boutht it to experiment with AIWB carry, and immediately knew it was for me (both the holster and the method of carry). I played around with position, and discovered that I like it right at 12:00. Also, surprisingly, after a few weeks of wearing it and playing around with the foam pad, I actually prefer it without the pad.
One thing I wanted to note, what really impressed me about the holster, is the perfect retention. I like retention a bit on the lighter side, and when I first got the holster, I thought I’d loosen the rentention just a bit, but after a few draws, I quickly realized it’s dialed in perfectly. The gun snaps right in, and snaps out nice and clean. It’s hard to explain, but I can grab the gun with two fingers and slowly pull until the gun snaps out, and the holster never rises with the gun (I hate when kydex holsters cling to guns, causing the holster to ride up). In other words, the retention is nice and strong, yet it doesn't "cling" at all.
For the last year, I’ve worn it everywhere, including many hours camping and driving.
