I purchased one of the AIM Surplus G-19s advertised several weeks ago. I just got back from the sandbox and picked it up today. Despite issues that at least one other member posted I could not be happier. WS prefix, August 1991, 2nd generation 2 pin frame. Minor holster wear, dead Trijicon night sights. The rear sight is positioned to hang over the right side of the slide, so either the shooter had issues or the sight was quickly changed before the pistol was surplused... and I could care less. This looks like a solid weapon, and I will post a range report tomorrow.
