I had N82 pro (kydex not stretchy) for my G26. It adds a lot of thickness to the gun. I measured the leather backing and the kydex (which is actually polycarbonate on the N82) with a caliper. Combined they add 0.34 inches which is a lot. Increases the thickness of a Glock by 20%. It would increase the thickness of a Shield by over 30%. Plus i didn't like that the backing extended all the way up behind the grip. It pushes the grip away from your body and makes it hard to get a good fast grip on the gun.

I replaced it with a White Hat Max Tuck which is awesome. Highly recommended. I carry my G26 in it now and I got a kydex for the Shield for once the CA model finally arrives.
