Thoughts on the Brno-made sidelock guns? The ZP series have chopper lump barrels, coil springs and a concealed third fastener. I have a 12 gauge with an English stock and extractors, which I think is decently well made, if not a bit plain. They don't appear to be as finely finished as some of the other European makers, but they do seem to have a lot going for them as far as function over form. Opinions?
