I've had one for about 3 years now. They are strong guns, handle well, and are generally well regulated.

As many of the readers of my posts have read, Chapuis sometimes as quality control issues. So you might want to have a gunsmith open the action and check it out if its a used gun (though $6k seems high for a used one). Also check to see what load its been regulated with. Most for the European market are regulated with 232 norma, and most Americans like it with a 286gr bullet.

The fit and finish of the UGEXs I've seen (including mine) is good, but not as nice as the PHs. The PH (and brouse etc) also come with some extras (extra folding leaves etc), nicer engraving etc. Though most I've seen were for the European market, so I'm not sure if the ones here in the US (Champlain, Chaddicks etc) are any different so take what I say with a grain of salt.

I am still working on putting pictures of my guns up, but will try...

Hope this helps!
