Like most CZ's, rarely and for a short time only.
When I bought my last three or four CZ's, I had a list of six or seven online gun stores and Gunbroker that I checked every day.
Lo and behold, what I wanted would come up and at a good price and I would jump on it. Usually shortly after my purchase they would be NIS again.
Just have to be patient and ready to buy. Too many people are finding out what a good deal CZ's are and it is making tough times even tougher.
