40S&W Korean made Glock mags= useless

[rhinoh]

I just got in two Korean made Glock 40S&W mags from CDNN.
These are 31 round capacity and were actually bought for my KelTec SUB2000(40S&W).
I cannot get more than 4 or 5 rounds into either mag!
They just completely jam up.
Email dispatched to CDNN to see what they say....
Anyone else had any experience with these?

Disassemble and check the edges of the follower for burs and file down or sand them a bit.

I have one... it's poo. It works okay using 9mm but not .40.

try loading however many you can, then slam the baseplate down against a table. That sometimes helps. Or it moves the jams later in the mag.

I bought my first Glock pistol and AR during the 94-04 ban. The pistol came with 10 rd mags, so I ordered a cheap (but not cheap) aftermarket full cap mag. The feed lips were not firm enough to keep cartridges from poping out. Not long after, when I bought an AR, full cap mags were available, but $$$, so I bought some cheap 20 rd mag (I think US Mag or USA Mag). These were just as worthless. In both cases, I wound up paying for quality pre-ban or just sticking with 10 rds. 10 rd mag that worked was worth more than a 15 rd mag that wouldn't. Lesson learned.

Well I was able to get 30 rounds in each by using a Glock magloader....what a PITA that was. I don't want mags I can't load with just my fingers.
Anyway CDNN sent me an RMA # today and said to send them back...but they didn't say what they were going to do. Refund? Send me two others? Pay for the return shipping at some point?
For almost $70 they cost they will be going back.

Better sell your Glock.All Glock mags need a magloader.Its why they include one with every Glock pistol.

I don't have a Glock.
But I have no problem loading the 15 round Glock mags for the KelTec with just my fingers.

Update- after repeated loading and unloading of these two mags I got them to the point where I could load them without assistance from a loading aid.
Tried them out yesterday in the KelTec and they functioned properly.

Never seen a mag so hard to load loosen up so much after a few cycles. Now that has me concerned will they lose too much spring tension after a few more cycles and again become useless

Never used one for my Glock magazines. They load fine by hand.

One thing I've found with aftermarket magazines is that sometimes if you replace the follower and spring with factory equivalents it helps. Even with a crappy Pro-Mag for my P95 a factory follower and a new spring made it just as reliable as any other mag I have.
