I was looking for a 1911 22 and thought of the GSG model but couldn't find one. I then check the web and found a Colt 1911 22 by Walther at Sportsman's Warehouse.
It comes in three models, the Government, Rail and Gold Cup. The Government was the only one that they said was available so I ordered one.
When it showed up I checked the box and there was the Gold Cup Trophy. Yippie.
biggest differences is adjustable sights, beavertail grip safety and commander hammer. It also has Pachmeyer wrap-around rubber grips. If it shoots as good as it feels I'm going to be very happy.
