Has anyone else ran into issues shooting blazer 9mm fmj? I’ve shot over 700 rounds of different types of brands of ammo with no issues but I was at the range and blazer fmj ammo made my glock jam 5-10 times per clip using the shields arms which I’ve never had any issues with. I took some federal fmj ran 2 clips through it no problem then ran some Winchester hollow points through the 43x with no problem and then load another mag of blazer fmj and it will jam again. Seems to me I think the blazer ammo is too long

Don't let them give you a hard time about using "clips" in a firearm designed for removable box magazines. They are just jealous because they don't get that cool "ping" when it ejects the clip on the last round.😉

1. What is the malfunction exactly?
2. Does it work out of the stock magazine?
3. Which Blazer Brass (115, 124 or 147)?

The 43 can have issues with ammo OAL. I have not heard about the 43X having an issue. On a 43 a magazine that could allow the cartridge to migrate farther forward could cause interference with the slide lock wich could lock the slide back with ammo still in the pistol. I just trial fit the 115 and 124 (Don't have the 147) in my 43 and they both have the potential to cause said issue. They are both considerably longer than the Remington 115 I used for comparison.

OP, we’re those 700 rounds fired successfully with Glock mags or PSA mags?

I had 2 PSA mags. One jammed a lot with Magtech and S&B ammo. The other worked just fine. I sent them both back because they both had polymer flaking internally.
The failing PSA mags were the first malfunctions that I have had with my Glock 48 with over 1000 rounds through it. At least 200 of those rounds were Blazer Brass 115 grain.
I was under the impression the Shield Arms Mags (Used by OP) and your PSA Dagger Micro Mags were different. Am I mistaken?

Sounds like a typical Shield arms/any aftermarket magazine issue... try the stock get back to us if they fail.. if it runs fine with the stock you foun d your issue... a non stock mag. Thats why I also never recommend the Shield mags..id rather have 10 rounds I know are going to work than 15 that may probably , most likely possibly work maybe ok-ish..

Too much of that when talking about those mags.. here is another example of it...

Some of y’all are just stupid.

Sure it’s a “mag.” But you know what he meant when he said “clip.”

It’s probably a FTF or FTE or both. But of course you need to bust on him for saying “jam.”

Take your self-righteous gun grammar corrections and stick it up your arses.

OP: I agree with trying factory mags and seeing if that works better.

It's a very Karen thing to do when someone new is posting.

Try factory mags. And what Blazer are you using 115gr ?

Gen 1, 2 or 3 S15's?
I've got Gen 1 and Gen 2's and I haven't had any issues with Blazer ammo, or any other ammo for that matter. Describe "jam" please. Failure to feed, or stove pipes/failure to eject?
You might want to call Shield Arms and ask for help with your problem. They have been very good responding to issues with their mags. I haven't tried the Gen 3 mags yet but they've addressed some problems with an updated design.
