I was putting an order in with my local Gun Range to purchase a new M357A1 since I sold my S40 to a forum member. After doing the check and price the Dealer was told it is a 2004 model. Is there a significant difference between the 2004 from the 2005 other than Manufacture date? Did Steyr change something I was unaware of? Merry Christmas and a Safe New Year to all!!
