If you bought everything that it has on it, sights, red dot, flash light, drum magazine, 2 thumb rests, 30 rd glock magazine . It would cost $600 or more. Id like to get $425 obo. Ive shot less than 50 rounds through it. Shoots slick. It's a Gen 2 that fits G17, 19, 19x, 22, 23,25,31, does not fit gen 5 22 or 23. Will ship.
