I have a few TRUE Bersa Thunder Plus 15 Round magazines.  This item has been the hardest item for me to find.  It took a lot of time and bugging Bersa to send me some of their Plus Magazines.  But these are Bersa Factory made Plus magazines, and not an after market reproduction.  It is the 15 round versions.  Asking $55 plus $10 shipping.  I am happy to combine shipping if you want more than one.
