Gun fit is everything regardless of whether you are shooting clays or game. So why compromise on an off the rack gun?
You can have the gun you want, in the specification you want made for you so it leaves the factory fitting you. No tweaking an off the rack gun, the gun is made for you from scratch.
Think of all the measurements that can be taken in a gun fit, these are passed to the factory (unless you choose to visit the factory). This cannot be replicated with a stock gun very easily.
All Zoli premium dealers can offer a gun fitting service in the UK or factory trips to have custom stocks measured and made in Italy.
