I buy most of mine on-line from AIM Surplus.
I bulged the barrel on my first 82 with a squib round of Silver Bear. I’m still a little leery of it.
However, considering the CZs were made to eat steel case stuff it’s nice to have the option if brass isn’t available.
I got my 82 back when they were $200 a copy under my C&R, two in fact. I should have bought half a dozen. Great little pistol.
