We recently acquired one of the new Magpul PMAG17 GL9 mags to try out and see if it equals a factory Glock mag.  As the flash flooding pics Shawn has put up on the Loose Rounds Instagram account show, the weather hasn’t allowed us to get any range time on it yet.  I have however taken some pics comparing the two.  Here you go…

Note, in all of these pics the Glock mag is on the left and the Magpul mag is on the right.
