They'd be the best if they could mold their holsters to correctly accommodate a safety switch for my Hk UPSc.
I use a C-TAC now and the holster's been fine but I don't view it in as high regard since I managed to break one of the clips. I am interested in their new Infidel holster but I've got a leather holster on the way.
They make great holsters, but I don't think they're the best. There's a reason other companies are still in business. If you want to limit yourself to pure kydex (no leather) holsters and guns that they have molds for, I won't argue too much.
I did that to both comp-tac's (xd and 1911) for about $10 worth of leather and glue from a hobby store.
