Huglu in Turkey makes these guns for both CZ and DeHaan to import. I like them really I do but they are all made on frames sized to the round and for me at least that makes the .410 and 28 both a bit too small and light. They are down right petite and I'm a big ol fat boy and they just don't fit me. I love them don't get me wrong but they just don't feel right in my hands. I've had their SxS guns in ..410, 28 and 20 and it took getting the 20 to find one that felt right in my hands.
I've not owned or held their O/Us except the 20 which really feels nice to me but I'm sure that like the SxS the 28 and .410 would likely feel too petite to me. Still I've not seen or held the smaller O/Us so cannot say for sure.
