CDNN has new glock mags listed as 4th generation. I was thinking that gen 4 were the last preban mags. AIM has them listed as "latest generation". CDNN is cheaper. What is the current correct nomenclature regarding glock mag generation



Any issues using current mags in my old glock pistols?

I use the latest generation mags in my G-19 3rd generation with no issue and my G-17 2nd generation with no issue.  I do not own a 1st gen Glock.  As I understand it the 4th gen mags have an indentation on both sides for the ambi-mag release.

I have no problems using 4th Gen Glock mags in my 3rd Gen G21.

CDNN is a good place to buy mags. A lot of times they have weekend specials plus lower shipping rates.

But, are 4th gen mags the latest modification?

From what I've read, the 4th generation mags are the most current being produced.

Currently, there are nine generations of Glock magazines.

But for simplicity, most vendors have grouped them into four generations.

Gen 1 = Non-Full Metal Lined with standard mag release cut
Gen 2 = Full Metal Lined with standard mag release cut
Gen 3 = Full Metal Lined with standard mag release cut and ambi-mag release cut
Gen 4 = Full Metal Lined with standard mag release cut, ambi-mag release cut and reversable mag release cut

Currently, all new production Glock magazines are in the Gen 4 format.

The only thing that the "4th gen" or "latest design" mags have is the mag release cutouts on both sides of the mag body to accomodate the switchable mag release button on the 4th gen pistols, other than that they are the same as previous mags  IIRC.

They will also work on every generation of pistol. However, older generations of mags will not work in gen 4 pistols if you swap the mag release button to the right side, if you leave the release on the left side older gen mags will work in gen 4 guns.

The "4th gen" is referring to the 4th gen Glock pistols. This means the mag is cut for the reversible mag release found on the gen 4 Glocks.

 



The magazine follower generation (which is probably what you're thinking of) is higher than that. I believe 9mm mags are up to a "6." follower now.







"4th gen" mag on far right:

Also on the 19 and 26, they stick out of the mag well approx 1.5mm longer than other mags. Give more purchase to rip it out if needed.
