Originally SIG (Schweizerische Industrie Gesellschaft) was Swiss, then merged with a German company which founders name was Sauer. Now I think they produce mainly in the US.
The SD in the name should be the German acronym for “Schalldämpfer” (silencer).
They also released the Tracy R figure with a golden MPX-SD, but due it’s fantasy look it sold worse, despite being the exclusive version of the figure.
I didn’t know the MPX’s entire front end was removable. I just used my fingernail to pop the rail panels off and on. They are held in place with two pegs each, and are easily removable if you are careful.
I’ve got one fully-loaded MPX with all the accessories included with the Tracy figure attached, and one stripped-down MPX with just the Troy sights fitted and the three rail panels removed.
They’ve been trying to sell that one more to police units as a modernized MP5. The SIG MCX Rattler has been tested with various units like CAG and the navy guys but not sure if it has gone on contract yet.
Didn’t see a thread for the new DAM Combat Girl figures (Lucy and Nana). DAM’s reusing the MPX-K for both of them, and it does not have the suppressor attached this time around. Also newly included is a 20-round magazine.
I’d make my own unsuppressed MPX, but I think DAM glued the suppressor on and I don’t want to chance it.
