I have used/still use a few Bobwhites ranging from 12 to 28ga. All work fine for the purpose those were built i.e. hunting.
IMHO, the Bobwhite is the better product that CZ offers among their line of shotguns.....mainly due to the configuration of double triggers. You may come across some with heavy triggers. I have one that turned smooth and lighter after some use.
The verdict on longevity, durability question is still far away as those firearms have only been in use since 2005? (I think). Nevertheless, it is my personal opinion that those are VERY (if not highly) acceptable field models.
Sharptail's review offers quite elaborate and honest insight into that sxs model.
