Both of those together may equal the value of a new Sig - but, be aware, if you are trying to trade it into a dealer - U probably won't get what it is worth.
He has to turn around and make $ too. One time, I bought a gun, shot it 1x, and had some issues. Traded it back in the next day - Only got 75%.
And, that was because I had gotten it from them the day before. Otherwise, I would have gotten less.
Now, the beneifit of a trade in is that you only have to pay tax on the difference.
But you may be better off selling each gun seperately on your own, and then use the $ for what U want.
