I guess sig need to fix there web site just like buds dont thank me. And your not sig expert ether and i guess the US Army need to fix the FMs and 2600 post in forum makes you nothingrlongnt is correct
the M11A1 is closer related to the sig p229 than the p228. The m11 is similar to the P228 though.
in the end. M11 A1 is not the M11. just like the 1911 is not the 1911a1.
and not trying to be rude, and thanks for your serivce but taking a weapons class in the us army and 4 combat tours doesnt make you a sig expert.
once again, thanks
