Does it come out each time you reload?
Don't do it !!
These things are just dangerous, and can cause your gun to fail to feed.

Honestly, do not put anything on to the body of the magazine. The extended length of a high cap magazine will do just find the way it hangs in your G23.
Show your Colts and Kimbers to your friends, show your Glock to your enemy.

Are you serious???
Uh... No. No this isn't true. Hell, Springfield includes these mag extenders standard with compact XDs. So does Ruger. A bit of plastic on the outside of the mag base isn't going to harm function in any way.
