I recently got my LTC Class A High Capacity license. I knew from my class that high capacity was 15 rounds magazines, but had to be pre-ban. Excited to get my first handgun, I went to a few different local gun shops to look for a high capacity used gun in like new condition. I found a used Glock 23 with two 13 round magazines LNIB for a very hefty price. I bought the gun as a carry piece and have been very happy with my purchase..... until this past week when I joined NES. After reading threads about high capacity magazines, pre-ban post-ban, I started to think about my two 13rd mags and if they were actually pre-ban. Seeing pictures of pre/post-ban magazines it became more apparent that these were most likely post-ban, they had the small rectangular cut out. I called a couple different shops to ask what they knew about the magazines and some said there is no way to prove if it is pre/post so I shouldn't worry about it. Well I was worried about it because it's a felony to possess these. I went to saw another dealer that is a former Police Capt. of a friend of mine who I felt wouldn't steer me wrong and he agreed these were most likely post-ban and if the SHTF it's my butt on the line going to jail. So the point to my story is Shame on me for not researching this area more before I bought the gun and Shame on that dealer for selling me something that could possibly put me in jail just for possessing them. I did just trade one out for a 10rd and the other is gone if I knew I would end up with just 10rds I would have just bought a Glock 27 with the +1 grip since this is a carry piece. Bottom line don't trust what a dealer says he most likey just wants to make a sale, research everything and make a more educated decision because its your butt on the line.
