I can't think of a quick, cheap, or easy way to totally remove it from the slide...
On a slightly different rant, I've always considered a magazine disconnect as something to avoid in a defensive handgun!!
IMHO, nothing good can come from one. If I accidentally bump the magazine release, I should still be able to use the one round left in the gun... That is unless I have the disconnect to keep me "safe" and transform the handgun into a poorly designed club. Really, the note should read:
"Be thankful we designed this gun to fire with the magazine removed"
Or for those poor souls who have a neutered gun:
"Caution, some idiot made this gun incapable of firing with magazine removed... Good luck with that!"
