i currently have four sports and there is nothing wrong with any of them yes they were expensive compared with what was availiable at the time but you see more hw 35s with knackered lock ups "well i have"the problem is people believe the breech bolt has to be tightened to death this is not the case the barrel should fall under its own weight .i like ian (hope he dosent mind me saying)have been arround a long time and in those years have stripped many different airguns and i have never seen any better finished internaly than the sport yes the original 45 is a nice gun but the angled breech is not a good idea and puts me off them as it traps the pellet skirt,
