I have a Blade Tech (
Blade Tech Holsters - Blade Tech holsters, knives and tactical gear for military, law enforcement, shooting competition and hunting) OWB. I carry a 9c every day and my holster is made for that one but I also use it in competition with my 5" CORE. You can see by the pics I've attached that I don't have any sight clearance problems and I haven't snagged the front sight on a draw (yet, if I do then I'll get a longer Blade Tech). Makes it kind of handy to carry my compact to the range and then swap the CORE into the same holster for practice or a match. The second picture shows the pistol partially drawn to show the sight clearance.
