I talked to CS at Airforce and blemished guns are covered by their lifetime warranty. I'd very much hope from a liability avoidance standpoint that airforce and midway would not sell dangerous guns. It would be way too risky $$$$ for them to knowingly sell guns flagged as blemished that are dangerous.
I snagged one for $858 and will report back.
Dang, another price drop!!! Oh well, I'm still happy with my purchase. Got the plain SS in .45 for $858. Has the same blem sticker. Only thing I saw was some light scuff marks on the moderator. Everything else seems ok. I did take the moderator off to bore site it and just by handling it the scuff marks disappeared. Seems to be a pretty good shooter too. Right now shooting NSA 290 and 350 gr. and holding a pretty good pattern at 50 yds. I'll stock up on the NSA 220 gr. HP and see how she runs.
