Gun from "In the line of fire"

Here is my version of the Gun from "In The Line Of Fire" The gun will cock and fire, however due to being a movie prop there are no firing pins and the barrel is blocked. You will need to print 2 triggers and 2 sears. Hand fitting required for the moving parts. Print an extra "Screw" and cut down for the trigger pin. The trigger tops need to be clearance so they can rotate up. Tools needed will be a 4mm tap and die for threading the assembly screw.Also you will need 2 ball point pen spring
