I still hold at 400, plus what the ammo is worth. Remember the gun shop owner isn't getting a lot of return on that, he's most likely giving you that price because he's making more on the 1911. He might get 50- 100 for it, if he waits, with it taking up room on his shelf.
I'm not trying to give you a hard time, I am a glock guy, have had many, currently have 2 21's and a 30. The 19 is the most popular and produced.
