Doesn't fit sig p320 m17 with thumb safety - DeSantis Thumb Break Scabbard Belt Holsters - SIG Sauer

Even after applying leather softener in an attempt to get the gun to go further down into the holster and, jamming a P320 m17 holster molding dummy into it repeatedly and leaving it there for days, the thumb-break snap cannot engage with the gun in it. The holster is otherwise well made and attractive so this is a disappointment.
