Gen 1 / NFML Glock Mags Cracked

their old and are a perishable item. Dang shame they aren't in good shape, they are valuable to Californians

I've not seen anything like that. How did you have them stored? Temperature swings?

In an ammo can, unloaded, in my gun room. Some temp swings but nothing drastic. Besides...that stuff should be impervious to the kinds of temps we're talking about.

It's a pretty common thing if you search around the web.

Not a Glock historian or anything so I have to ask, are the pistol frames made of the same material?

That's the $64 question. I don't know the answer to that. If it's not the same it's probably pretty close.

Plastics generally get more brittle over time (my understanding is that it has to do with the plasticizers "evaporating" over time), so it probably wasn't common when the mags were newer, but is becoming more common as they age.

Back in the day, the Glock geeks said they called them polymer because "polymer" is a material and "plastic" is a property of a material.

This. I collect vintage desktop fans, and the plastic parts on them are hard and brittle as a rule. To the point of crumbling under finger pressure. Unless they’re made of Bakelite, which is a precursor to what we call “plastics” - then they can be pretty solid even after 100 years.

You know, during the ban, as long as one original part remained form a preban mag, you were allowed to “repair” them with new parts. IDK if that holds true in the states that still have bans in place but it might be worth looking into. You might be able to sell those to someone behind enemy lines vs. tossing them in the bin.
