I own a CZ Bobwhite 28 Ga. SXS, a DeHaan S2 SXS 16 Ga., a Weatherby SA08 28 Ga., and a Stevens 555 28 Ga. O/U. Only problem was a broken leaf spring on the Bobwhite; however, I bought it used from an owner who shot it A LOT. A gunsmith repaired it with no problem.
Turkish guns suffer a bit of snob prejudice and some mechanical failure on the first early imports; now rectified in the newer models. Also, the lower price point guns (like USA lower price point guns) can have problems. Stick with CZ (GREAT customer service) or a recognized name importer and you will be fine.
