Does anyone know where I can buy one of Sig Sauers pistol grips that come with their new M400, 516 and 517. I picked up a used one from a gun show and it fits like a glove. The only problem seems to be its not sold anywhere. I called up Sig Sauer and the rep didnt know what I was talking about, she assumed I meant the Magpul grip they used to ship their guns with or their SB brace. Am I stuck to scouring gunbroker and ebay?

Yes, although I would try calling Sig again and talk to somebody more knowledgable. Sig may sell an individual one, but I doubt they wholesale them separately for retail.

I might have one in my parts bin. What's it worth to you?

Any good sig dealer worth their salt can get it for you.  It wasn't easy but my local shop got me replacement grips for my P226.  He said he had a hell of a time getting the part numbers but once that was done ordering them was easy.

@TCBA_Joe --- I'd be willing to put down slightly above what most of the aftermarket grips go for these days, maybe 40 bucks?
