No. That's a rather oddly designed "tuckable" holster. The clip could have been designed to attach to the eyelets in front of the trigger guard so the end could be nearly flush to the barrel. Looks like someone's early attempt at Kydex.
It just needs a new clip made and the excess material trimmed off the end and it could be functional as IWB.So that it is not a total loss for your particular need of functionality or comfort level, is it possible to remove the belt clip and reattach to the back converting holster to OWB? I realize that your desire is to have an IWB holster but this might give you another carry option option as you have already ordered another holster and might save this holster from the dreaded drawer of unused holsters?
