Have been hanging out for a while now and love this forum keep up the good work.Looking to swap my slightly used 2nd gen model 17 to a friend for a 26. My 17 has probably 200 rounds thru it with reg sites and 3 Hicaps. The 26 in question is new or like new. It is not his gun, but he is trying to broker a deal so that he ends up with it for this trade. My question is this: What would be a fair deal? The 26 and cash? The 2 guns even and the deal on the mags? Don't know what to do. Ideally I would like to end up with the gun, some cash and 1 mag. Anyone give me some help
