I sold a perfectly great Glock 19 because it had lost favor to a Springfield XD-9 Service. A year later I had sold the XD and bought a G17 AND G26. I have other nicer looking pistols but keep coming back to the durability, reliability and simplicity of the Glock when it counts. I wish I still had that Glock 19.
The Glock 26 will be my concealed carry piece as soon as my license comes in the mail.
Moral of the story - Be sure your pistol has permenantly lost its favor because you may very well wish you hadn't sold it.
To each his own.
