I have 6 brand new flat base 8 round HK factory magazines for the HK45C or USP 45.  These flat bases make the gun extremely concealable with out that extra pinky tab sticking out.  I am asking $59.50/each plus $5.99 to cover shipping.  USPS MO or PP with 4%.  If you have any questions, please ask.  x_ra_y@yahoo.com   Any discrepancy you see in the pics are from oil from the factory on the magazine.  Contact me by email as I am posting on more than one site. Thank you.
