Hi guys, if anyone fancies a crosman 600 i have all 3 variations for sale all excellent ,about 27 in total ...if i have any problems with the guns i send them to lawrie for fettling,, all are guaranteed so any problems and you can send them directly back to lawrie,, to be honest i like all 3 variants the 3rd being easiest to gas up ,the 2nd variant actually has a hole in the end cap as the co2 capsule goes in neck down and seals like a modern pistol up agains a urethane washer..just mentioning the various triggers they are all exactly the same in pull and weight,just the later ones have alloy instead of a cast type..and the safety is not a problem on either type as i never use it,...it only holds the trigger forward ,gun can still fire if dropped or the sears break,,
