I just ordered this about an hour ago, supposedly the same as a Sig Mosquito just branded with their GSG label instead of Sig's. It was $179.99 shipped to my ffl. I was told by a friend that GSG made them for Sig and they were stupid expensive with their name(Sig)& Logo on them https://palmettostatearmory.com/ati-gsg ... 10tff.html
I first saw this thread this morning. This evening at Rural King I saw one so I just had to have it! Thanks to you I can tell you it feels great in the hand and looks nice also. I will have to take it out back and check it out in the next day or so.
GSD did manufacture the SIG mosquito. Yes they wanted a lot of Coin for that. There some others. Walther made one for Colt that came with a threaded barrel. If that new GSG will run at that price you got a deal.
