Federal Aluminum Cased Ammo in a Glock

Does anyone have a problem with their Glock's reliability, when using Federal Aluminum Cased 9MM Ammo?

Heck, I wasn't aware Federal even made such a critter...

I don't shoot much factory ammo, but I'm curious too.

I'm sure that it's really just CCI Blazer since Federal and CCI are parts of the same 'company.'

As I remember it, I think that many cautioned against aluminum cased ammo in the earlier Glock 40s (because of the 'poor' chamber support underneath).

I shoot both 9x19mm Glocks and .45ACP Glocks, but no 40s. Having said that, I don't use aluminum cased ammo either, so don't have any stories to tell about it in Glocks.

A quick Google search yielded the consensus that Aluminum cased ammo is just fine in Glocks.

It must be true if it's on the internet...

Hmm, Better ASK GLOCK.

If Glock doesn't know, Then be damn careful, experiment at your own risk.

I have seen some alu-minium cases at places I go to shoot now and remember
seeing cases in Alaska in the 80's, it was then I thought it might get popular, moved back to lower 48 and thought it was a passing thing.

My Old one-- If in doubt, leave it out.

I dont have a problem with aluminum cases in any of several pistols and calibers. As an experiment I reloaded 45 acp cases, firing them in a 1911 and they would make about 5 loadings before the case mouth split. Ymmv

You are the first person I've ever heard reloading Al cases; I've been always told they were one use only.

Walmart has brass cased federal for $19/100 - why bother shooting aluminum or steel?

I've always had luck with aluminum case ammo in Glocks.

I had no need as I have plenty of brass to reload, just tried it to see if I could and how long it would last. The 9mm and 380 aluminum cases are handy as I dont have a need to find the expended cases. They size easily as well, just the necks give way quicker then brass. I guess I should stste this was a light/target loading...no max loads for sure!

Mileage does indeed vary.

The 45s may split earlier than that depending on the chamber.

The 9s work tolerably well though. The indication to me that they were approaching 'do not reuse' status was soot appearing at the lip of the primer pocket and, yes, about five firings is when that started to happen.

They do run through the size die like butter though. And a pack 100 rounds feels considerably lighter than a 100 rounds loaded in brass.

Again, interesting research.

9mm Fed/CCI Blazer Aluminum case

I have never had a problem in my Glocks, however a buddy had the bullet stick when "press checking" and it dumped powder in his action. Of course it had to be cleared with a Squib rod and cleaned. However he rarely (never?)cleans his Glock.. He also reported Stovepipes during a class.

I had an Aluminum case head separate and damage my 9mm AR15 conversion block, and it was difficult to clear. I went to a forged lower and use Brass case if its close in price, which it is now!

Good point! Any of the blowback operated carbines put a lot more stress on the case than a gun that uses a locked breech.

My AR 9mm doesn't like the reloaded aluminum cased stuff. Too much friction for the way my carbine is set-up. The gun gets sluggish pretty quickly.
I had no case head separations and the recovered shells don't show bulges at all - but my gun doesn't like the stuff.

Also on that note: I sure wouldn't put any (new or used) aluminum case ammo into an H&K fluted chamber.

Must've yielded a good result.
