If I was interested in getting into some silhouette shooting, which should I acquire, the Lux or the American? I'm mostly curious about should I bother with the Lux that has the iron sights, or go straight to the American (or another model you guys would recommend) for the reduced weight of not having iron sights on there. Are there other considerations I should be taking into account between the two models? I know the Lux has a slightly longer barrel. And if someone knows, where can you source the CZ or Leupold 11mm dovetail rings in Canada?
