Hey Evan, sorry for your issue. I carry my large Buck Knives (110 and 112) in these, all of them. I think what you're having an issue with is the break in. These are designed to form fit to many popular knife sizes, once you fit your knife in, the leather will start to form fit around the knife. Then remove the knife, pass your belt through the opening, then slide your knife back in. You will notice that it's much tighter (at first) until the leather relaxes some. After a couple days you notice the knife starts to move with just the right pressure and it's all broken in. It just may take a few days to get that custom fit, but it works beautifully!
