Looks like I'm the unfortunate SOB in this instance - got two on order.
If they don't work out, I'll return them. I'm very comfortable raising a stink.
I learned this lesson the hard way. Trying to help others avoid the same mistake. Refusing the delivery is probably the best option.
I bought 1 of those mag from CDNN or Classic about 5 years ago. Nothing in the listing showed the "mfg CZ" stamp or the seam on the back of the mag. Since I often carry a vz82, I needed reliable mags and those weren't. I eventually gave it to the "SnagMag" magazine carrier people in hopes that they could make a carrier for it.
