I read from time to time about "drop free" Glock magazines. Are there different types of Glock magazines out there? I would think that all magazines would be drop free. Please clear this up for me. Thanks!

Some of the older ones are "Non Drop Free" or NFML (Non Fully Metal Lined).

Personally, I HATE NDF mags (I have several). There is a reason they were made this way, but the logic of such escapes me.

The only logic that I can think of is that you can sell more mags because no one in their right mind would want NDF. I have a few - only because they came with the weapons and they are clearly marked range mags.

IIRC Austria only issued one mag with a pistol and it was designed that way so the Soldiers wouldn't lose it.

It's not that hard to believe , when I started in Police work , standard loadout for your duty revolver was 18 rounds.

I also remember reading the non-DF was for magazine retention. I'm glad we've got the DF mags now. THey seem more well constructed and more sturdy as well.

ndf - old school shit... the older g17s didn't drop free like they do now. you have to reach up and pull the mag out with your fingers. the newer drop free mags will drop free in it though.

Ok, thanks for explaining that to me guys! I understand the logic even if it does seem kind of a dumb idea. I have a follow up question. How can I tell the difference between the older non drop free mags and the new drop free mags?

I have both . The drop free have a little window in the plastic showing the metal liner. Right where the trigger would be on the frame

I still find the glock dfm the least drop free mag out there. my p220, m&p45 and p7m8 mags fly out of the guns compared to my g19 mags. there is still room for improvement from glock.

That's only the newest ones. Alot of FML drop-free types don't have that window.

There is a pic on here, somewhere showing the distinct differences. Someone will pop in and post it, I'm sure. I'll look to see if I have it.

The older non-drop free mags will have a "solid" looking baseplate, that is, no hole in the bottom. And the early ones (which is most of them) will have no caliber marking on them, as at that time Glock was only making 9mm mags.

There's eight generations of Glock magazines.
Here is a pic, showing all eight generations.

Generations 1-3 are non-drop free.
Generations 1-4 are pre-'94 ban.
Generations 5-6 are during the '94 ban.
Generations 7-8 are post-'94 ban.
Generations 8 is the current production with the ambi-mag release cut.

Drop free - no swelling - push mag release they drop = faster reloads

Good for CCW but not needed for the range.

I have the 2 NFML mags came with my G17 back in 90 and one +2 mag that I bought at the same time. They will drop free when empty. They will not drop free when loaded.
