Sorry for my English
Can you help me?
We have a separate sub forum for the non-M&P semi autos, but we can overlook that since English isn't your first language.
The 5906 and other 4 digit model name S&Ws are considered to be 3rd Gen. Your pistol was available with that adjustable rear sight, but the Novak style rear sight (adjustable only by drifting/pushing it left or right) was probably more common.
The 3 digit model name pistols (439, 459, and 645) are 2nd Gen.
The 2 digit model name pistols (39 and 59) are 1st Gen.
