Fn 509 tactical. Comes with two 24 round mags, optic plates, and 2 different backstraps. I want to trade for other optic ready 9mm handguns. Guns at the top of the list would be a canik rival darkside, p320 platform depending how it is loaded, 2011 pistols, optic ready vp9 tactical. Feel free to make offers. Im willing to add cash or accessories for guns that hold a higher value. Just let me know what you have. $700
