That's a good idea. :yes: 
Don't you have more then one? Use one for you hand gun on key ring and keep the one from the carbine with the carbine!That is a good idea, but isn't it more simple to just keep it on your key ring, like I do.....
This way I have it for all my HP's and even some others that require a screw driver tip, if you will.
Not trying to be honery, just helpful.........
