I'd think stiff to start with is ok too, IF you pull it from the pocket a lot to break it in faster. Also, I am thinking deep FORMING is not too good an idea with pocket holsters. I made one for an LCP and it's not easy to get the gun out! But, mine does not have the nice "hook" piece as shown above... that should catch on the pocket and keep the holster inside while the gun pulls out. Mine turned out nice, but, not effective... so it's a show piece.... not for carry! I need to make a proper one now!
