Did you ever find out if the all black packs were tied to your low serial # ps90?Since I've been handling a lot of trigger packs I've noticed 5 distinct types. I have pictures of all five types I'll have to post ASAP. I've never seen the all black one, so that would make a 6th type. I have a PS90 who's serial # indicates it is one of the first thousand, and it's not black. Are black ones limited to the first couple hundred units? Does anyone on here have a black one?
Is this true?
I understand--- mine is a generalization of what I have seen.Colors do not mark generations. Colors only represent a new run on parts used to build the hammer packs. Don't complicate part design changes with color of parts changes.
Gen 1 Post on primary sear for return spring.
Gen 2 Shelf on primary sear for return spring.
Gen 3 Notch cut on hammer is higher.
There are no other generations.
A change in the color of the sear or hammer doesn't change the generation of the hammer pack.
Generation changes are changes in design of the parts, not changes in colors of the parts.
If you want to use colors, there would be more than 10 generations. Translucent hammers, orange hammers (not aftermarket), gray hammers, black hammers, white hammers, brown sears, green sears, gray sears, white auto sears, black auto sears, etc etc etc. I have personally seen all of the above colors in hammer packs yet three things remain the same no matter the colors. A post on the primary sear, a shelf on the primary sear, or the notch placement on the hammer.
