Ok, sounds like we're not talking about the same holster. The #3 I have has a clip, not a j-hook. #3 is leather, #3K is kydex. Deep cover holster, IWB, entire thing hangs below the waistband. I use this because I wear a polo and khakis.mr.72 wrote: K3 is Kydex. The leather version is the "#4". FWIW I think I am going to order a leather snap-loop to replace the ill-fitting J-hook on my K3 (drill out the rivets and put in Chicago screws).
