lol.... not nice to trade in problem guns. Your Glock 19 sounds like easy fix with recoil spring change. I would get a new recoil spring for it then list it on grunbroker.com get about $700-$800 right now because of the panic buying then buy that Colt commander new somewhere else. I wouldn't trust a used gun for carry.
Has Taurus really spent more on shipping customers their firearms back to them than actual sales?
