I have two of the black Buck M-9's and both of them have a "silver" edge from sharpening at the factory. This "sig" model is all black which makes me even more sceptical. Like maybe it was totally refinished or parkerized somewhere else and then engraved. I'm not gonna bite and leave this one for someone else. Just my opinion. Probably a mistake on my part but i guess i will live and learn! Ha!

I've been known to spend some stupid amounts of money for bayonets that I want. I'm a little hesitant without additional information on this one. I will admit that it is a very good job and it very well could be a authorize SIG accessory. It would be nice to have some confirmation of that. I'd like to know who has bid the thing up to $550 this early in the game. I don't like the hidden bidder thing.

M9 Bayonet SIG markings
 

Also, if it was SIG authorized wouldn't the box that the bayonet came in indicate this somewhere on it? Too many unanswered questions to make this a safe buy.

No necessarily. The SIG marked 1987 Buck M9 that I got directly from Switzerland was in a standard geen Buck box. If SIG purchased commercial bayonets and marked them I expect they would put them back in the original box.

Additional Information
 

When I couldn't locate this bayonet with any of the US SIG distributors I figured I might as well go right to the top. I contacted Sig Sauer directly through their website. It took several days but I heard back from them this morning. According to Mr. Ray Carter at SIG SAUER, Inc this is not a SIG accessory.

So, I'm not sure exactly what it is, but it looks to me like someone did a very fine job of etching a commercial Buck bayonet. I placed a call to the seller last week but only got his voice mail. I left my number with him but did not get a return call. With the information I have on hand I would place this bayonet in the same catagory as the S&W bayonets currently on the market. A nice novelty for $50-100 but certainly not worth more than that.

One of these days I will etch the words "CARLO'S CONTRACT" on a standard commercial Buck M9 and I will put it for sale on ebay .... just to see how high will go its price .......... :grin:
Back to the topic: to be honest I'm quite worried about this.
Should this be confirmed, how long will it take to have a "chevron" mark added to a second generation, flat top, three line M9??????? :confused::confused:

You're right Carlo. When these bayonets start to demand prices in excess of $1000 there may be people who try to take advantage of the novice or uneducated collector. The only thing we have going for us is that it would be more difficult to engrave a chevron to look the same as the original stamping on the blade.

SigSold
 

If the bayonet is a spurious one, and considering it went for a good sum, greed will eventually produce another that magically appears out of the woodwork. I would keep an eye on the seller & see what other unusual items he offers. I failed to mention perhaps a query to one of the Collector Forums dealing with modern assault rifles might shed some light on this M9. I can recall in the 1970s how rare the SIG PE57 bayonet was. You could only get one if you purchased a rifle, and back then a loose bayonet could command about $200.00 (you can buy a fistfull of them for that now)...

OK, who won the auction?

Been in the same position, if this was a genuine article I am surprised that no one on this forum especially Bill has ever seen or heard about it. I just wonder if "Sigmund" knows how much his blade is going for :nanabang:
