A method of making a two piece pin type electrical connector contact comprising the steps of: stamping from a sheet of metal a rectangular shaped piece; forming said rectangular piece into a sleeve having an axial opening running the entire length of said sleeve, a rear open end portion and a forward closed end pin shaped portion, the diameter of the opened end portion being greater than the diameter of the closed end portion of said sleeve; cold drawing from a piece of metal a tubular member having a rear open end portion, an enlarged middle portion having a forwardly facing shoulder and a rearwardly facing shoulder, and a forward closed end pin shaped portion, said diameters of said forward and rear end portions of said tubular member being slightly less than the respective diameters of said forward and rear end portions of said sleeve; radially compressing said sleeve so that the axial opening in said sleeve is reduced, thereby reducing the diameter of the forward and rear portions of said sleeve; inserting said sleeve into said tubular member so that the closed end portion of said tubular member surrounds the closed end portion of said sleeve; and punching a wire stop and inspection hole through said sleeve and member in the open end portions thereof.
