AyA also made the XXV in a sidelock model. I had one in 20ga. Very nice gun, but I did not shoot it for crap. Combination of too short/too light I think. Had the same problem with an XXV boxlock Ugartechea 28ga a number of years back. Imported as a Parker-Hale by Precision Sports. Lightest gun I ever carried in the grouse woods, but the grouse were mostly safe.
