It's for a baby eagle. The paddle is soft leather, rough side out. Not dishrag soft, but pliable. The 'rib' across the paddle isn't to give it rigidity, it catches the underside of the belt through the pants, and helps to keep the holster from coming out of your pants when you draw. It's needed - the holster is boned tightly enough that it will retain the loaded pistol when held upside down and (lightly) shaken. That are a heavy gat!
A modified steel spring clip is sewn to both the paddle and the holster to keep the holster from being floppy. No exposed metal or seams inside the paddle. There are some stitches, but they are recessed to avoid irritation.
Dennis, it would be a simple matter to add something to the plastic paddle with contact cement. If you'll mail me a tracing, I have some thick suede that might be suitable. I could cut and send you a piece. But the plastic is still going to be rigid regardless.
