Has anyone had issues with your G48 jamming/misleading when using Shield Arms 15 round magazines? Once my gun gets warm, it will jam every third to fourth round. Didn’t occur with OEM magazine and mag release.

Welcome to the community. I can’t answer your question I don’t have any Glocks but for me 9 times out of 10 any failures it’s the mag.

If you have had no problems with the Glock mags, then the problem is likely the new ones. Not an uncommon problem with many of the aftermarket mags.

Thanks Robert. Have researched the issue a bit and there does appear to be a problem with the Shield Arms magazines and the Glock 48. I put the gun back in the original configuration and heading to the range to see what happens.

Welcome to the family brother @William842 and you are blessed to be here.
In my experience, by far and away the best way to get a Glock to malfunction is one of two things
*Modify it with a non-OEM part (including magazine)
*Use reloads
If your Glock is not mechanically stock, or you are using reloads (or Winchester), and you have malfunctions, the very first thing to do is revert it to mechanically stock and shoot decent factory new ammo. Then go from there
I see you are planning just that. Report back how it goes.

@William842, you haven’t mentioned, so let us know:
- what magazine release catch are you using with Shied Arm magazine
- is S15 mag a gen1 or gen2 model?

As @Jerzees is getting at with his first question - The metal Shield Arms mags can cause extra wear on the standard plastic Glock mag release leading to malfunctions. If this is the case it might lead to continuing malfunctions even with the regular Glock mags.
You can add the Shield Arms metal mag release to solve the problem. But that release may put extra wear on Standard Glock mags. Mixing and matching mags without swapping releases should probably be avoided.
I use a variety of off brand mags in my Glocks for practice. Have actually never had a malfunction with KCI or Magpul. But I still only use Glock brand mags for defensive purposes.

Thanks to everyone for the advice. I also put in the SA mag release (that they said would fix the problem). It didn’t. Since the 30 return period has expired, I’m going to eat the cost and go back to the OEM configuration (didn’t have the problem with original mags and release). The problem was so bad with mis-loads that I had to drop the mag and rack the gun, then reinsert the mag and re-rack. Then gun then would jam three or four rounds later. Not a good scenario in a self defense situation. Would definitely come in second place. Again, thanks everyone, I appreciate all the help.

@William842 hello and welcome
Have you contacted SA anyway? I heard they’re customer service is supposed to be really good.
I just received my S15 Gen 2 for my 43X but haven’t tried it out yet.

Karacal,
Yes, I spoke with customer service and they were very responsive. They offered to have me ship them back for analysis and repair, if necessary. As I mentioned, I didn’t have this problem with the OEM mags and release. Hope the Gen 2’s work out for you, but I can’t have unreliable mags with serious jamming issues. Going back to the old, reliable OEM mags and release.

Update: I put my Glock 48 back to OEM specs (mag catch and magazines). Went to range and shot 150 rounds and the gun performed flawlessly. I hope others using the Shield Arms 15 round mags have better experiences than I did. I no longer trust the equipment to be functional when I need it and keeping my OEM configuration.

Not a first time we hear about third party accessories being not reliable.
But…if Glock would like to use them by default…it won’t be a Glock anymore. 
Friend of mine has been shooting G43x with S15 mag and metal mag catch without single issue.
