Opinions Please: While doing a little research on the 21sf ambidextrous magazine release issues, I read that some think the Ambidextrous, Picatinny model may be considered collectible. I also read that Glock will replace the gun if you send this particular model back to them. So my question is: Is there enough potential for "Collectibility" in this 21 to warrant keeping it intact or should I just go ahead and send it back? I'm either going to sell it and purchase a new one, or send it back to Glock for a new one to avoid any future magazine release issues. I just don't want to send it off to it's potential demise if it has collectible value to someone else.
