One member referred to 'The GunRack' in Burtonsville as CZsRUS -- very apt description.
it's been a while since I've visited, but they always have a strong supply of CZ pistols and rifles.
Given you live in Sharpsburg, you could try 'The GunCenter' in Frederick, HOWEVER, they are not releasing on-time (waiting for ND back from MSP) which will put you in the HQL fiasco and many folks find their prices high and their customer service lacking. YMMV --
I do everything I can to keep my business local - but given the deadlines, consider purchasing online and transferring in. Bollingers will treat you well (based in Taneytown) as will Hafers (closer to you in Downsville).
Just call both before you purchase so you are clear on the process. Given the crunch, a couple of industry partners have had to suspend in bound transfers.
I was in the Gun Rack last week and they only had two CZs! They said CZ got some big contract and haven't been shipping much to dealers since the beginning of the year. I think they had one, customized CZ75B in stock for something like $1200. Even Gunbroker.com doesn't list many CZs nowadays.
