I picked up my VZ from my ffl today. Very happy with it. It does indeed appear to be Czech made. 15 1/2 inch chrome lined barrel with pinned extension. Barrel has proof marks. I will have to have it milled to double stack. It has a nice paint finish. The trigger guard is VZ2008 style. The sporter stock is nice, but I will change it out.
I think this is a good deal from SOG International. I would recommend it if your in the market for a VZ 58.
