Magazines are one of the most critical component to reliable operation of a semi-automatic handgun. For that reason, I usually stick to factory magazines even if they are a bit on the expensive side. However in many circumstances, aftermarket magazines offer benefits that the factory magazines do not.
I have a box full of SIG brand magazines for my Sig P320 pistols, but when Elite Tactical Systems Group announced that they would be producing magazines for the P320, I was interested.
ETS Group is best known for their transparent polycarbonate Glock 9mm style magazines. I have used several and found that the ability to quickly see how many rounds I have left in the magazine is a great benefit.

The Pmag 21 GL9 looks identical to the Pmag 17 GL9. The Pmag 21 extends from the bottom of the Glock 17 in order to make room for those four extra 9mm cartridges. The Pmag 21 also has 10, 15 and 21 round witness holes in the side.
The Pmag 21 GL9 uses the same floor plate as the Pmag 17. This includes the “dot matrix” marking area. This also means that the Pmag 21 will accept the Magpul L-Plate rubberized floor plate. If you are not forced to work within competition magazine length rules, the L-Plate is a worthy upgrade for these magazines.
