I found a used Uggie Gr I 20 that had been cut to a 12" LOP w/ pad, thus limiting its market appeal rather dramatically.
I believe wt is just over 5.5 #s.
With the Fiocchi trainer shells, recoil was fine for a 9 yr old; I only gave him 1 shell for quite a while, too.
Start her on dead straight away hand cocked clays, throw 'em exactly the same way every time, and let her break as many as she wants that 1st day...it's all downhill from there.
Have fun.

Always looking for small bore Francotte SxS shotguns.
