Another question comes to mind about the HW50S. If the spring gets weak, which I assume they all do at some point, is it possible to get an upgrade kit ( if you could call it that ) with a gas piston that is adaptable to the HW50S? I plan on doing a lot of hunting with this gun (if I decide to go with it ) so it'll be seeing some prolonged spring compression, although I intend to keep it minimized as much as possible. I also intend to put a lot of pellets through it at home also. I haven't ordered the rifle yet, they are on back order and aren't due in for a month but the sooner I get on the list as a paid customer, the sooner I'll get a rifle when they DO arrive.
Although, if I decide to go with the .177 they have those in stock....I'm still on the fence with that.
