Just thought I'd add this here. I don't have the GSG 1911, but I do have their MP5 clone. I bought it in 08 or 09 maybe. Fired thousands of rounds through it and just cleaned it last week for the first time.
GSG makes a great product, and I wouldn't hesitate to recommend their stuff.
"If you remember nothing else about what Iím about to consider here, remember this: the one and only reason politicians, bureaucrats, and policemen want to take your weapons away from you is so that they can do things to you that they couldnít do if you still had your weapons."ó L. Neil Smith
