My Glock 19 did not like Blazer Brass. Why?

Typical symptoms of a low power round.
Try to clean and lube the gun. The problem will likely go away as the spring loses a bit of the initial strength.
 
If you're determined to use Blazer, and it continues to exhibit signs of being too weak to be reliable, you could use a lighter recoil spring for practice, and switch back to the regular spring for carry purposes
 
My gen 3 Glock 19 cycles Blazer Brass just fine.

I will say that Blazer Brass seems to be very inaccurate out of my Walther P99 (which is a tack-driver with most ammo, and has proven to be more reliable than the Glock).
 
My guess is that your not getting a good seal in the chamber upon firing--either too much or too little--either way not having enough recoil energy to both extract and cycle. I know it sounds silly--are you sure your thumb may not be riding up on the slide lock lever while gripping/firing?
 
It happens...try another brand ammo.

Try another grain bullet.

Clean it like the dirty dog it is, try the same ammo.


Break it in more...assuming it's new.

Point is don't sweat it.
 
There are many Glock Armories around I would hunt one up and have them look at your Glock. Take some of the Blazer brass along also.
 
I know it sounds silly--are you sure your thumb may not be riding up on the slide lock lever while gripping/firing?
Not silly. My shooting buddy had the same thought, but it still did it for both of us after being extra careful to not do that (and I don't think I was before).

Point is don't sweat it.
Right. Not sweating it yet. If it happens with more regularity with more kinds of ammo,then I'll start sweating it.
 
When I first entered the handgun market in the early '80s, the gun magazine writers were most all on the revolver-only-for-self-defense bandwagon on the basis of functional reliability. Those few who would admit to it being acceptable to buy a semiautomatic for self defense would caution the need to ensure the gun fires reliably with your choice of ammo, and that one should expect to take a semiauto to a gunsmith at least once to iron out any bugs. Today's semiautos are far more reliable and gun manufacturers far more willing to guarantee that their products function.

I see you having four basic options:

- Shun the offending ammo and enjoy your gun (no hassle and cheap).
- Send the gun back to Glock and hope they fix it (a hassle).
- Take the gun to a local gunsmith and hope he fixes it (expensive).
- Sell it and get another (expensive, but perhaps fun if you like to shop).
 
The previous answer to just avoid the ammunition is the cheapest thing to do.

If you're going to use the gun for self defense, the only thing you should be interested in is whether the gun will reliably shoot your self defense ammunition of choice. If it does that - you're okay.

I had exactly the same experience with a SIG P229 - it refused to extract 115 grain Armscorp ammunition brass about every 5-7 rounds. The ammunition would run reliably in four other 9mm's - but, not in the SIG.

I had 8 magazines - it didn't matter - it happened with every magazine.

I saved the spent brass, measured them against SAAMI standards + other manufacturer's ammunition and could find no obvious difference.

My solution was to not shoot the Armscorp ammunition in the SIG.

It's certainly a bit disconcerting to find a brand of ammunition that doesn't work as it calls into question the gun's reliability - but, as has been pointed out - some guns just don't like a specific brand.
 
Me and my roommate recently took about 500 rounds of Blazer Brass to the range and had multiple FTEs on my Beretta 92s, and his 92 Elite1a. Weirdly my LC9s had no problems with the ammo. Also shot about a hundred rounds of UMC with no problems.

We didn't bust out the micrometer or anything but on quick inspection, the walls of the fired Blazer Brass seemed to be noticeably thicker than the walls of the fired UMC Brass.
 
Honestly, I think it's weird that the OP's Glock 19 doesn't cycle Blazer Brass. I've never had a problem with that ammunition in a variety of handguns, including out of Glock's, 1911's, XD's, Kahr's, Walther's, etc... I say this because for a long time about half the ammunition I'd shoot is Blazer Brass. It's pretty consistent ammunition. Is it the best ammunition? No. Is it the most accurate? Nope. Even Blazer Aluminum has been fine. The only brand of CCI in general that I have ever had real issues of any type with is Blazer .22 LR. It's perfectly fine in bolt action rifles (again not the most accurate), with 0-3 duds per brick. I don't shoot Blazer .22 LR out of semi-automatics any more because it is inconsistent and tends to be on the weak side.

Otherwise, 115 grain Blazer Brass should be right in a Glock 19's wheel house. It should eat that up.

I'm no expert on Glocks, but I'd guess that his Glock is slightly finicky because it is new. Maybe shoot some hotter 115 grains for practice and plinking for a while, like Fiocchi Shooting Dynamics. You can still get decent prices like $13 to $14 a box (try Midwayusa). It zips along at 1250 according to Fiocchi, which puts it into pretty hot territory for practice ammo. Just make sure you know the fps/ft lbs when buying Fiocchi. Sometimes they aren't labeled real well if you buy it in a brick and mortar store.

Blazer Brass isn't as cheap as it used to be, so I've been veering away from it to buy slightly higher quality Fiocchi or Sellier & Bellot. Magtech is also good and cheap. Or Speer Lawmen is quality, too--and by the way, they brag about having CCI primers...

Of course Hornady is good, but I usually won't pay unless I am doing target shooting or hunting.

Just about the only brand I would stay away from, oddly, is Winchester White Box. I've had numerous fail to fires/duds out of a variety of handguns and calibers with this brand. Other Winchester products are probably fine.

Anyway, this was way to long winded and aimless, but what I am saying my only real complaint about CCI Blazer Brass (centerfire Blazer, really) is that it is dirty and it isn't hot. But it seems danged consistent to me.
 
No matter it's how the Glock handle's the carry type Ammo. that counts. I always make sure my handguns can handle the carry type Ammo.s,if I have problems with some range Ammo. I understand it's not Mfg. with the quality of higher costing carry type Ammo.

Myself I have never had any problems with Blazer brass Ammo. and I have used it in many of my handguns same with their aluminum cased Ammo.s

But many items might change from many groups of Ammo. production runs.
 
That's great and all, but testimony that your Glock doesn't have a problem doesn't provide anything useful to the OP regarding problems with his Glock.

Gee....really?

Who relieved themselves in your corn flakes this morning?
 
Which Generation of 19 is this? How long have you owned it?

I believe Glock's initial run of the Gen4 had some issues with the double captive spring that they later rectified, but that would only have affected you if you ran out and bought one when the first came out or got it from a source that got a first run.
 
Gen 4. I think test fire bullet as Dec 2014 and I got it mid January. So this thing is pretty fresh off the assembly line.
 
Slim, you mentioned that it didn't "seem" to be mag related. When I have cycling issues, magazines are the first things that I inspect.
