Yes it is a clear "ETS" brand Glock mag, but this firearm accepts most Glock 9mm double stack magazines and most glock mags are black (Glock brand and Magpul) and their reasonably priced too

Timothy, yes Sir. Here is a better picture of the ETS Clear Magazine : etsgroup.us/ETS-Group-Translucent-Glock-18-mag-p/glk-18.htm

Timothy, yes it is clear, but you can always buy non clear, it takes Glock type magazines.

Most of these will fit (except G43(x), G48, and G26)

YES, the magazine IS clear ... the same as the picture. I hope this helps
