So i called kimber about running aluminum cased .45 ammo..

Were those cases actually stuck or just being stubborn?
It's no surprise that aluminum will expand more than brass.
Did you show her not to just fiddle with the ejector on that revolver - but give it a good smack?
Show it who's boss.
Some folks have the idea that their guns are fragile.
 
FrankenMauser One thing that matters to me, but hasn't been brought up yet:
Aluminum cases (even when coated) pick up dirt and grit a heckuva lot better than brass (or even steel).
That additional abrasive action will cause premature wear to parts of the firearm that come in contact with the case.

Nonsense. Absolute nonsense.
Where the heck do you store your ammunition....loose in the bed of your pickup?:rolleyes:



Last year, I gave some .38 Special a shot. 14 rounds is all that went through the revolver. Extraction went from difficult to "where's the hammer?" in no time. And the cases visibly scratched the chambers.

It must be pretty sorry steel to be scratched by an aluminum cartridge case.;)



I have never seen an aluminum casing in the "exemplar" envelope.

I transfer 2,000 guns a year, every Glock had a CCI Blazer aluminum case.



Perhaps you are mistaken, and are confusing proof load casings with Blazer aluminum casings.

In eight years, 14,000 firearm transfers I've never seen a proof load case included with a firearm.



Proof load casings are tin coated (to differentiate them from other loads, and to aid extraction). They typically also have a red lacquered case head, but the coloring often flakes off after being fired.

And what manufacturer includes that case?:rolleyes:



I admit that there are some companies out there that do not proof test their firearms (or even do standard-pressure testing), and may be so cheap as to have used Blazer Aluminum ammunition for their "LE sample case" test fire.
But I have never seen such.

Buy a pre 2015 Glock.;)
The days of the little envelope with a fired case are drawing to an end. Maryland finally got rid of that requirement a couple of years ago.

I've shot hundreds of rounds of Blazer aluminum in .380, 9mm, and .45 ACP in semi auto guns with no issues. Those are the only calibers I shoot it in. Shoot lots of it in 1911s chambered for 9mm and .45 ACP and it performs fine.
 
You called Kimber and they didn't give you the answer you wanted to hear

No, they didn't really give him an answer at all! A "no" without a reason why is not an answer. Just a CYA statement.
If you ask someone, most anyone, for permission to do anything, the default answer is almost always "No." If I tell you "no" and something goes wrong, you can't come back to me and tell me..."You said it was OK."

Certainly would tell you not to use reloaded ammo also.
 
"...suggest that aluminum cases might rupture easier..." Ever heard of Federal or CCI(same owners) being sued for Al cases causing anybody grief?
The real issue with Al cased ammo is its lower quality and non-reloadability, not anything it might do to a pistol.
"...Aluminum cases (even when coated) pick up dirt and..." No, they don't.
As mentioned, Kimber's response was a CYA response. Al cased ammo won't bother your pistol.
 
Don't listen to these people encouraging aluminum cased usage. Any non-reloader should always use brass cases. Don't worry about policing them up, I'll take care of it.
 
I seem to remember asking Kimber years ago a question regarding the use of steel (nickel cased) ammo, (not aluminum) in their guns...and was told not to use it. So I didn't.

Springfield Armory stated that the use of steel cased ammo wasn't recommended for use in their EMP.

I've transferred quite a few Glocks myself, and I've never opened any of the envelopes that have the cases in them. It's the customer's gun, it's up to them to open it. Your statement makes it look like you've opened every single fired case envelope that came with every Glock you've sold, and that seems pretty odd to me.

Your supporting argument is very convincing. :rolleyes:
I don't care what Kimber's opinion is (even in regards to my Kimber). It is plainly obvious that their response was a CYA action; and expecting anything else would be irrational.

What I (me, this guy, yours truly) care about are the abrasive properties of aluminum and its tendency get abrasive particles embedded in the porous surface.

I used to work on aircraft for a living. I've seen dozens, possibly hundreds, of aluminum alloys, from clean and new to old and corroded, come in contact with everything from Plexi-Glass to titanium, from rubber to magnesium alloys, from braided hydraulic hoses to phenolic resins, from polyester fabrics to high carbon steel, from acrylic to copper, from other aluminum alloys to fiberglass; and the list goes on...

There is one rule:
The other material always loses. Sometimes the aluminum loses, too; but the other material always loses.


If you want to stuff cheap, nasty ammo wearing an aluminum casing into your firearms, go right ahead. I won't stop you, or even tell you that I don't think you should be doing it. But I will no longer do it with my own.
As mentioned more than once... that's my opinion on the matter (based on experience); and the actions I plan to take in the future. Your opinion and actions can differ.

Missing the point about foreign substances. That, or just being overly obtuse.

I don't buy dishwasher safe handguns. So I've never had the opportunity to check their cleaning solvent sample package.

Sounds like you need to pay closer attention. Nearly every new, American-made revolver I purchased between 2008 and 2013 had a proof load casing as the exemplar.
There's also at least one 9mm proof load casing packed away in a box, from when I purchased my Ruger P95.
Proof load casings are not the norm, but they do get shipped.

I've owned at least a dozen Glocks personally, both new and used......that makes it pretty easy to open up MY FREAKING envelope that came with MY FREAKING GUN.;)



It's the customer's gun, it's up to them to open it.

Yup, and quite a few open the envelope, flip through the owners manual, field strip the slide, look down the barrel of their new gun and even go "pew, pew, pew" while I finish the paperwork.

That's an erroneous conclusion.;)
 
For giggles I opened up the envelopes from the Glocks I have currently. For the 2007 it was CCI aluminum, for the 2008 it was CCI aluminum, and for the 2012 it was Blazer Brass. I'd looked at my HKs before but never these particular Glocks.
