Ahh, someone else has also discovered this!
So far I've bought three of them off GB.
First one has some wear on it, night sights were toast, 3 mags, over all is quite good shape- $236. Gave it to a friend for half that, since he was jonesing for it and gave me a threaded barrel for mine. Plus, I enjoyed hunting for a new one
Second one appears new, no internal/external wear, 100 rounds at most. Night sights are still great, 3 mags, and came with a CT laser grip - $280. EASILY an $800 gun new.
Third one also appears new, same as above but no laser this time - $305. I was being greedy with this one.
So far I love .40S&W. This is a great time to get a pistol like this while the Internet is busy telling people .40 is no good anymore.
this is about as close to actual "military surplus" value as you can get with handguns right now.
