I got my G22 a while back, and want to get the scope that Walther USA shows on their website. It's a 3x9, rubber armored. I've searched the net and eBay with no luck. They don't indicate that you can buy it directly from Walther. Anybody know where to find one -- or the equivalent? The reason that I think I probably need the Walther scope is because any scope you mount on the G22 will presumably need long eye relief, and I assume the Walther scope is engineered that way. Thanks.
