Hello! I have two 4006TSW CHP and an older 4006 CHP without rail. The control number on TSWs are "E7xx1" and "E0xxA", the older 4006 has "COASTAL #x".

I understand that CHP's older 4006s usually have control numbers start with A/B/C/D, followed by 4-digit numbers. I am wondering that mine was one of the loaner guns which used to belong to CHP's Coastal division, for I have seen the pictures of CHP's older 4006s with control numbers like, "NORTHERN #x", "VALLEY #x", "SOUTHERN #x", "BORDER #x". I would love to hear from someone who can educate me with the information from CHP.
I have also seen a CHP's older 4006 with control number of "ACADEMY #x". Was it be a loaner gun of the CHP's academy?
Are there any 4006TSW with control number start with CHP's jurisdiction division and/or Academy?

Also, would someone confirm the M&P 40 is the new sidearm for CHP?
I deeply appreciate your kind help.
