My friend keeps asking me to post this for him.. He wants 700 OBO. .. I owe him a couple hundred dollars, buy it for $600 today, and I'll cover $100 of the purchase price for you... So he wants 700, you pay 600, I give him 100. I don't know much about Glock, I think the mags are 22 round, 13 round, and 10 round... Includes everything in picture. Located by PCC Sylvania.
