I have the small kydex sheath the Scrapyard sells. My DMCG fits in it fine. I originally got it for the YKCG but was never happy with the fit. I tried remolding it but was still never happy. It sounds like the knife is going to far down into the sheath. If that is the case you should be able to heat the kydex (get instructions from one of the dogs that regularly works with kydex) and tighten it around the top. If that's not it yours was cut to short and needs to be replaced. I can measure mine tonight and let you know how long it should be if you'd like.
