Trust me, all viable manufacturing businesses build to a budget, even Purdey. Speaking as a retired businessman I guarantee that Zoli, Perazzi and every other ongoing gun maker does the same. What CG got right was to pick their market segment and build a range to sell successfully into it, so did Perazzi, Krieghoff and various others before them. Sadly, Zoli, like several other Italian makers, don't seem to have identified where in the market their products fit. Something which has led to the disappearance of many, many gun makers over the years. I'm sorry to have to say this but issuing guns to a handful of trap shooters is no substitute for proper product planning and marketing.
Q1: How many open days have Zoli held? No idea, probably none!
Q2: How many open days have CG held? No idea but certainly lots and lots!
It doesn't matter how good the guns are if (a) No one knows much about them and (b) They're only attractive at deeply discounted used prices. Because without sales of new guns, the used market dries up.
