Please forgive my ignorance, and for resurrecting an old thread.

I'm considering the purchase of a 9c, but when I handled one the other day at the store, I found the grip to be unacceptably short. My pinky hangs off the bottom, and I won't have a CC gun like that.

So Google brought me here to this thread.

My question is this: Which magazines do these extension devices work on? Do they provide a finger extension for the original 9c magazines, or do they provide what is essentially a finger "filler" for a full sized 9 magazine?

If the former, then one would be using the original mags that came with. If the latter, then one must buy new full-sized mags and finger extensions too.

Is my understanding correct?
