I am far from a Contender expert, owning just one in 223 with a 4x Swift scope. BUT, What about trying an intermediate eye relief scout rifle type rifle scope? Might work for you. Back in the late 1980's I used to shoot on the department range with a guy who was a National handgun silhouette champion. He used a Contender on occasion, chambered to some small (hornet based?) round, using a standard 6x rifle scope. His off hand shooting stance placed the gun inches from his eye. Recoil was very mild. I would be leery of using his method with even a .223 level of recoil. It worked for him though, as he was fond of showing me when I started thinking I was getting pretty good.
