I am WAY new to both this list and CZ's so I hope this is both useful and "legal". I happened into a gun shop and they had a few "relic" CZ's. Again I am new to CZ's so the relic stuff is way above my pay grade but, if there is interest they were at the Northfield Gun Company in Northfield Ohio and I have no relationship with the store. To my very unedcuated eye they looked kinda like 380's in sub compact and I think he referenced them to WWII.
I may correctly or incorrectly remember 27's?
