I have a custom RD5 & a TAK (1095). The Ranger definitely fits the bill for your needs, but it's a big & heavy knife. The TAK is lighter & probably a better CC knife because of its thinness & weight.
Personally, the best CC fixed blade I have, & use, is my RAT3 D2. It's definitely made for CC & their sheaths work. A little "boot clip" comes with it, which I use to carry mine IWB behind my back, & it comes with a TekLok.
I also have a MercHarness, but I haven't used that yet. Both knives are great choices. Have you thoght about asking Justin about his RD3.5? Someone on some of the knife forums (Don't know if it's on this one), has been trying to sell his custom RD3.5. Remember, Justin measures his knives from tip to end of the sharpened blade, not tip to handle edge like many other makers do. For example, my RD5 could be considered a 6 by others.
Anyways, good luck.
