Howdy.
I bought a Sig P228 about three weeks ago. It's NIB/plastic lockable case, and came with 2 Klinton mags. The gun is apparently assembled here in the USA, and did not come with a test target/shell casing. According to the info I got from a Sig-specific board, the gun I purchased was a Military/LE over-run. It is difficult to date the manufacture of these guns because of the lack of stamping ( the older german made 228s had specific stampings).
Mine had arrived in an unsealed bag, with a blue "Sig" grip tag and the inspectors tags strung to the trigger guard.
All in all it's a nice pistol, but as I posted elsewhere, was somewhat dissappointed at my initial groupings. Needs more break-in time. Hope it performs as well as the 220. Need to work up a good load for it.
