Brand new here, joined basically so I could ask a question. I purchased my first FN ever in the form of a Fnx-45 (non-tactiCOOL) at a great price under $700. However it came with 10 round magazines instead of the 15 round. I've disassembled the magazines and noticed the catch that limits it to ten on the walls of the mag. Is it possible to remove these and convert them to 15 rounds? In case anyone mentions it, I live in a free state. 15 rounds mags are good to go here in North Carolina. Thanks for the help in advance !
