Problem with new factory magazine

[2A43]

I got a brand new Glock 22 and 3 mags in January. One of the mags failed to feed yesterday. It did not push the last round up high enough to be chambered by the slide. My shooting instructor told me to go buy another one because I'm out of town at training. I took the mag to the gun store and on the way I noticed that the follower catches on a piece of plastic inside of the mag. Its part of the molding at the top of the mag that comes down on the inside of the metal body. Its on both sides of the mag but the follower is only getting caught on the one side. Its difficult to see in the picture because of the light. I took the pic with my camera phone. I don't have my crime scene camera here with me or I could get a much better pic. I circled the problem area in yellow in the picture.

Just want to know if anyone has experienced this/ make people aware of the possibility of the follower catching on this and not feeding the last 1 or 2 rounds.

It's hard to tell from the picture, but it looks like a #4 follower in a #7/#8 follower mag tube. The SAME thing happens if I try to install a #4/#5 in a #7/#8 mag. If this is a "new" mag, it could be "new" old stock because #8 follower is current I think. Also, has the follower been changed out to a #4? Does the bottom the mag show any wear like it was removed?

I didn't know the followers had to be matched with the mag body. I guess I need to start marking mine. There were several of us who were issued new glocks and 3 new mags back in January. I used it several times in a shooting range where several other officers were shooting at the same time and we do drills where we are shooting and moving. At the end of a drill, there are mags everywhere and we all just grab 3. The all have a few marks in the base plate because dirt gets in them from dropping them on the ground and we clean them out. Its very probable that the body and follower were swapped around.

2A43,

There is a possibility that your follower does not match your mag body. That's something to investigate. And if it does not match, it will bind near the top as you indicate. If you've a dept. armor, he/she should not make a follower error, and if h/s did, that armor needs schooling. Agreeing with cole, that's a number "4." You've either been issued old stock or an old mag... or the follower is mismatched.

However, I have experienced ticking inside the mag and on the follower of new magazines that duplicates the problem as you describe. This molding process ticking is generally near the top of the mag where the polymer molds atop the steel mag liner, then the follower has a bit of ticking that binds against it.

As a precaution, I always disassemble new magazines and remove the ticking inside the body and on the follower (not too much, just enough to make things work). This has eliminated the FTF issues caused by the molding process. Or you can just keep using the mag until this problem smooths itself out, and it eventually will. But, you indicate that this is a duty weapon, I suggest to take the mag apart and smooth it out... especially since you say that you can 'see' where it's binding.

Marking and numbering your mags is a good idea... it's standard practice in my parts. This allows you to identify 'your' equipment. Also, if a particular mag is having issues, you are able to single it out for repair or trash.

Hope this helps,

Thanks for the replies. I asked one of the armorers here and I checked with some of the guys with different model glocks from different departments (I'm at a state course) and I found out that the number 4 is from a glock 23 with a 13 round capacity. Apparently at some point in time I picked up a mag that was improperly put together. It was probably a mistake made by someone at home who has more then one model glock and put the wrong spring in the wrong mag. After thinking about it, I think I know who did it and I will check with her when I get home. As for trimming off the plastic molding to get this follower to rise to the top, I tried that today and the follower did rise to the top, however, it doesn't seem to have sufficient spring pressure to push live rounds to the top since the spring was supposed to be inside a smaller magazine.

I did mark all of my mags to help prevent/eliminate any future problems. Thanks for all the info and suggestion.
