Never used a "Scout Specific" scope, but plenty of handgun and regular scopes. I think the real difference for any forward mounted scope, whether on a rifle or handgun is eye relief. Not all pistol / scout scopes are the same. Measuring the distance between your eye and the scope you want to use, as mounted, in shooting position, is important. Higher magnification powers lessen FOV, and make proper eye relief even more important to avoid the dreaded "blackout" when looking thru a scope. Most manufacturers list the optimal eye relief for the glass they make, making it easier to choose the right one for your specific need.
