Pam 1392 deployant clasp
 

I hate the fit of the tang on the short strap tang. Does the standard strap on deployant wear smaller?

Pretty sure OEM Panerai Tang and Buckle Straps cant be swapped to a Deployant
You need to buy a Deployant Specific Strap when you buy the clasp

Happy to be corrected, though

You are correct... straps for deployant buckles have thinner tails.

Yup, won’t work. Deployant is an entirely different strap.

Right, but the tang standard is too big for me and hate the short strap tang. Will the strap for the depoyant wear shorter?

Cant speak for PAM Clasps but every deployant clasp i've ever fitted wears bigger
Have you considered an aftermarket strap/buckle?

My wrist is 6.75” and the rubber deployant straps wear shorter, can’t speak to the leather.
