Ahhhh...OK, now I understand. (Takes me a while sometimes...)
As others have mentioned, it all depends on how well the holster was fitted. I've seen different makers' holsters for the same exact gun sometimes be a wee bit tight, sometimes a wee bit loose...
My personal preference is leather, with the gun contacting the rough (flesh side) of the leather. When properly boned and fitted, the gun should slide home with a barely-felt *snick*, and when the holster is NOT on the belt, the gun should be just a bit loose...maybe 1/16" of play. When you put the holster on, and tighten up the belt, the leather then gives just enough to provide a firm friction grip, but the gun will draw easily.
Never had a Blade-Tech, so I can't really offer advice. If its a full Kydex, I would assume that there is probably an adjustment screw, with which you can provide more/less friction to keep the gun holstered? If so, maybe loosening up on that just a touch would help alleviate some of the holster rub, but the gun will get some, regardless.
