I don't know if this question has been answered but, how can I tell if I have a 1st gen or a 2nd gen sigma?
The 1st generation is the SW9F/SW40F. 4.5 inch barrel, no accessory rail. The 2nd generation is the SW40C/SW40V/SW9C/SW40C/SW357V. 4 inch barrel, no accessory rail. Some SW40Vs and SW9Vs have a grey polymer frame. The third and current generation is the SW9E/SW40E/SW9VE/SW40VE/SW9P/SW40P/SW9G/SW40G/SW9GVE/SW40GVE. They have 4 inch barrels and accessory rails.
