Thats strange. This is an ex club gun complete with open sights that I picked up last night. Its in very good condition. Ive just put a string of 10 shots over my SKAN chrono and its not dieseling. Its doing between 593 - 598 with RWS Superdome so bang on with the power for an Arnie 335. Recoil is very light with no spring noise but I will have to play with the trigger a bit to get it to my personal likings.
Very pleased.
