I have a fab defense kpos pathfinder set up for glock.it is extremely well built,aluminum not polymer set up.just put your glock pistol in the chassis and you now have a personal defense weapon capable of 100 yrd shot out of your pistol! Has flip up sights and comes with case,single point sling and I added a shockwave blade to it.the shockwave blade does fold.no mods to your glock are required. From pistol to pdw back to pistol in secounds,had a red dot on it and it holds zero everytime..I payed 700 for this 4 months ago asking 400 or best offer. I don' run glocks anymore is the only reason for sale.text or call anytime, no email please.3374595602
