These are Commando Funebrero's Socom 45's, one with laser sighting and one usp45 with mounted light. I replaced the regular 45 and the python with them so you can have both in game at the same time.
Install Instructions
Using Spookies' IMG tool, find and delete colt45 and Python .dffs and .txds then 'add' the new colt45 and Python .dff and .txd... have fun!
