A long shot, but let's try...

I have a 6 round P380/CW380 steel base/flush fit magazine that I would like to trade for a 7 rounder with the plastc extension.

Or, I'll sell it for $25 shipped.

Cash, check or money order only. I do not use paypal.

There are often posts wanting to make this trade in reverse. Someone wanting your flush mag will be happy to trade their extended mag. I haven't searched the forum, but you may find such requests in the queue.
