Nice! I got an early SN CZ50 for $210 last Spring from SOG and they're currently selling the CZ70s for $200 but with only 1 mag and no holster (and it's a crap shoot, even with the $10 hand select). I would guess this is worth around $275-300 with the extra mag ($25-30), a non matching box ($5-10) and holster (?). If it's really unissued then you'd certainly be north of $200 for the pistol. Just a WAG on the total since I don't know the current value of the holsters. I'd do some ebay/GB market research on the holster if I were you. Personally, I'd have a hard time paying more than 20% of the value of the pistol for a holster, but I'm not speaking as a hard core collector of these Eastern Bloc pistols. Some of the guys over on the CZ forum may be quietly drooling, who knows
If you keep it, they are fun little guns to shoot. Not much kick with that .32 ACP, 7.65x17mm Browning. My wife and step-daughter enjoy the CZ50, and that's not meant to disparage it, I'm just saying it's a non-threatening shooter.
