I'm sorry, but why would you trade your Glock 19? The Glock 19 is one of the best defensive pistols out there. 9mm ammo is pleantiful and still fairly economical, especially compared to 44 special. Glocks are extremely reliable and the finish is very durable. With the night sights and 15 round magazines, the Glock 19 is a great concealed carry gun. You should seriously reconsider parting with it.
The ATF should be a convenience store instead of a government agency!
