Been thinking about using a Meteor spring in the Hawk as well. Jim Maccaris Meteor spring is superb in my old meteors, and as the Hawk is a 25mm/1" piston like the meteor, it seems like a sensible choice.

How do you ensure that the floating guides do not end up all the way forward in the piston? Do they reset position with every cocking stroke?
