Hello i have a glock 20 gen4 for trade i bought it brand new less than a year ago. It has trijicon night sights,johnny glock combat trigger, it's had the grip chopped to point more like a 1911 and stipple, I also have over 500rds of ammo to throw in. I would like to trade it for an ar9 that takes glock mags or a ruger mark iv tactical. Primarily those but open to other options.
