I recently bought a Hidden Hammer Super Belt Slide Holster for my 642. I like the holster except for the "internal locking device" that fits in the trigger guard. It makes it difficult to take the gun from the holster sometimes. Maybe because it is new. I see no need for it, since it has a thunb break to hold the gun in the holster, but I don't see a way to remove it without ruining the holster. Any ideas or comments?
