LP, I've seen some of the HS guns and the grips definitely look re-finished. All the ones I've seen have been a light/cherry color, high gloss. This definitely has timing/lockup issues by the looks of the cylinder, and the one I handled also had a CCH loading lever. As for the SB trigger guard...unusual. IMHO, asking WAY too much for a used brasser with no case, box or papers.
I would pass unless you really have a jones on...a couple hundo more would score you a nice sig series Colt.
