Well, I've worn it all day today, and man is this thing comfy! Retention is good for CCW, but I don't think I'd like it if I was LEO. The holster doesn't move around at all, and like I said before, the concealability is surprisingly good. I can hide it under a t-shirt (my P7). I am about 5'7" or 5'8" with the physique of a heroin addict. Quality seems excellent.
Oh, and I forgot to mention that I got the horsehide, not the cowhide. Don't have much to say about the mag carriers yet, as I haven't really used them.
