4006
Cant tell you an exact age, but I can tell you the transition to the 4006 began in 1991. The 4006 was replaced in 2007 by the 4006TSW, so that should give you a ball park idea of the age of your pistol, I'm sure someone on the forum will be along shortly to give you an exact number. When issued our pistols at the academy, we received no box, but the ones I saw were plain white cardboard. 3 magazines, and some aftermarket cleaning supplies. Oh and we are the California Highway Patrol, not the Highway Police.
