I am going to be trading a SIG P226 (9mm) with E2 grips for a SIG P290 + $400. I got my SIG 226 for $629 (after tax) and I am looking to flip the P290 as soon as I get it. Do you think I could get $300-$350 out of the P290? OR should I ask for more/less? I was hoping to get at least get a net $700 when it is all said and done, but if I can squeeze for more I will... I mean, who is going to turn down the chance to make a little more?
