I drank the poison and bought a Glock 42 not long ago, and 1 of the mags and a loader was for a 9mm Glock 43. (I think) When I called Glock, they sent me a new 42 mag and loader, so here's your chance to get a free mag and loader, complements of the company. All I ask is that you're a supporter of the site. Check the pic out and make sure the number on the mag for your gun is the same as this one. It's the one on the right.
