I'm being offered a 92 f for $400.00 with box, papers and two mags. good deal or not?
Thanks!

Night sites? Amount of rounds fired? Overall condition?

With limited info given $400 sounds high...$320 sounds better

no night sights. almost new condition. don't know round count
yeah, i thought  $400.00 was a bit much

I would opt for a 92fs for that price. New ones (92fs) only cost around $500.00

Already have a FS. Was just thinking of adding the 92f

I guess it depends on what part of the Country You are in! I know a Guy at the Gun Shows that will buy 92F all day long for 500.00 in the Condition You Mentioned that one is in. I recently bought My second 92FS like New for 500.00 I personally would not Hesitate to pay 400.00 for the 92F in the Condition You say that one is in. I had a 92F and never had any Issues with it.
The only difference is the FS has the Safety installed so the Slide won't fly off if it Breaks. It funny Beretta Never Recalled the 92F Handguns. You would have to Shoot that 92F an awful lot with plus P Ammo before You would have to worry about the Slide Breaking.
I was a little disappointed to see this 92FS has A Plastic Trigger, Safety, and Mag Release! Neither My 92F or My first 92FS had any Plastic on Them. Now I have to spend a extra 60.00 to buy the Metal Replacement Kit that Beretta Sells to upgrade all the Plastic Parts!

Here in TEXAS, guns are a little higher than normal cause of the culture and demand. If you don't have a boat load of weapons (pardon the pun) you might as well be a Kalifornian  

I'd love to see where you can find NIB 92FS's for $500. Here they're in the $560+ range, with used, like new going for $499. There was a recent sale at a local shop for $539, and that is the lowest I've seen for a new 92FS.

$400 for a LNIB 92F is a screaming deal.

I agree completely. It is the same way price-wise out here in NH. One ain't gonna do better than $560 out the door for a new 92FS/92G out here.

Keely Arms has NIB 92G's for $499 in stock.

That is good and all, but when you factor in shipping and transfer costs for it to go out of state (if that's applicable) you are going to end up very close to the $560 I paid out the door for my 92G just a short time ago. I wouldn't pay over $600 for a 92G, but in many cases buying online is not always saving people as much as they might think, although YMMV, and perhaps considerably.

$400 wouldn't be bad around here.

Fair price.  Not a screaming deal but reasonable.
