I wonder if anyone shoots their HKs with CCI Blazer aluminum case ammo. I have a P7 PSP and will get the P2000sk 9mm and HK45c in the future.

Will the aluminum cased Blazer do damage to my HKs in any way? I know steel cased ammo is a no-go. Thanks.

No. It will be fine.

The majority of rounds that Todd L Green shot through his HK endurance guns was Blazer aluminum, IIRC.

THIS ^

However, if at any point you have issues with it feeding or running reliably, you should be aware that HK specifically advises against the use of aluminum-cased ammo in their guns. They are designed and guaranteed to work only with quality brass-cased ammo.

Will the use of aluminum-cased ammot void the HK warranty? Anyway, what's the HK warranty that comes with a used and NEW HK pistol, respectively?

My first and only HK pistol so far is a P7 PSP bought from HKparts.net. I was told the PSP comes with HK USA warranty but not sure what's and what's not covered.

Officially the pistols are warrantied for the original purchaser. There are many documented cases on this fine site of HK honoring their warranty on used guns however.

If the P7 was one of the police trade ins I believe they have an additional extended warranty, but I'd ask The seller to be sure. Todd has always been up front and easy to work with in my experience so I'm sure you'll get what you need from him.

I have several USP .45'S and with the current ammo prices over the last few years when its range time they get fed a steady diet of Blazer Alum. Not one hiccup. In college I used to feed my USP nothing but Blazer as well so I am either the luckiest man on the planet or you are good to go brother. Stuff actually is pretty clean too for cheap stuff. In my experience HK's are hard to choke.

Is there any steel cased ammo warning in the HK45/HK45c Series Owner's Manual? I always assumed it was, but cannot find it in there.

Put around 5-7K rounds of every type of ammo made (including Blazers) through my P9s without one malfunction of any kind...not one! Have fired 500+ of all sorts of ammo (including Blazers) through my other HK's...again, not one malfunction of any kind...HK's eat everything...NO COMPROMISE!!

I think You should prob read the manual considering it doesn't mention anything about using brass at all...infact what it says "there are no known .45ACP ammo types that are not compatible with HK45 pistols". Which means steel.
Hey, easy there friend. . . Some of us have been hangin' around here a little longer than you, and that has always been the official HK word on it. I wasn't tryin' to be hard or short with you, just direct about the point you wanted to know. I haven't read every single Operators Manual revision for every pistol. Every Op Man I have seen over the years has stated it clearly. But I assure you that I am giving you good info. Don't forget. . . you asked. (and I still think yours prolly says it)

Actually, if you read the USP, P2000 manual, and others it specifically says "HKI pistols are designed to function with quality manufactured brass cased ammunition. The use of steel or aluminium cased cartridges is not recommended, and could affect the safe and reliable functioning." This is under the ammunition section of the manual.

As another aside, if extractors become out of spec and cause malfunctions due to various reasons (steel cased ammo being one of the reasons), orfeo is the guy to chat with. Since you use steel, you may want to keep that bridge unburned for the future.

Just because you've been on this sight for a while doesn't mean your right about everything on this sight. I wasn't being short with you just suggesting you should prob read it because when u read the ammo chapter my question of using steel is totally relevant. It DOES NOT mention brass. It's says my HK45 can shoot any .45 ammo no issues. P+ ammo will wear pin quicker but steel, aluminum all good and can eat any ammo. If I had the $$ id buy the good stuff bit since I'm just target shooting the steel $.30 rnd is what I like.
steel ammo...especially TulAmmo is absolute garbage...search ANY forum for ANY handgun and you will see opinions pointing to various issues--splitting cases causing malfunctions resulting in broken extractors and stuck empty cases in the chamber...also have read several people pointing out that powders in foreign ammo can sometimes be corrosive (surplus AK ammo for instance...) meaning you will likely want to make sure you're keeping up on cleaning...

The Blazer Aluminum is decent stuff...but for a minimal extra cost you can cycle brass...and not wear out extractors and firing pins as fast

Cheaper is usually the opposite of better...in this case "cheap" ammo is going to cost a lot in worn parts and downtime
its your gun do what you like but a little bit of respect will go a long way when opinions are asked for....especially in this group...

I have put 1000 rounds of Brown Bear 115 gr. through my P30LS with no issues, and would have no problems continuing using it. From what I've read and been told in classes, steel's greatest issue is poor quality control, rather than any intrinsic shortcomings, outside of the thermal expansion issue. The issues with the extractors apparently is a non-issue, since the steel used in steel-cased ammo is suppose to be very mild.

First off it's "site" not "sight" learn how to spell if you're going to puff your chest out at Orfeo like that.

Orfeo is a well respected member here and I'd take his word seriously.

To be completely accurate the NEW HK45 manuals do not mention anything about non brass cased ammo. But ALL other HK's do. Including my brand new USP45. So you can see why he said what he said. And yes he's been here longer and I would think that means he probably knows a little bit more about HK's than most of us.

Aluminum ammo will not hurt your firearm at all. HOWEVER it is not as good as brass. Stay away from Winchester white box and Tula. You spent $1000 on the handgun. Can you afford $.03 more per round?

Actually, you can find Aguila brass cased ammo on the web for the same price as the Blazer aluminum case. Personally, I've never had any problem with Aguila in 9mm or .38, which are the two calibers in which I've shot it. In fact, it was recommended to me by people here.

If their centerfire ammo is half as good as their 22LR I would agree completely...

As far as running steel-cased or aluminum-cased ammo is concerned, you aren't likely to harm your HK with it. The aluminum cases are WAY too soft to harm your gun for sure. The steel cases MAY possibly be harder than the brass cases that your gun is designed to run on, in which case a person could make the argument that it will increase wear & tear on your weapon. However, the reality is that the steel they use to make cartridge cases is necessarily a soft alloy. . . MUCH softer than the steel in your HK.

The next consideration might be buildup of bad crud that you don't want in your gun. It is possible that aluminum, being so much softer & more fragile than brass, might rub off and build up inside your gun at a faster rate than brass would, eventually causing issues. I have heard this theory brought up, but in my opinion it is very unlikely to become a serious problem. Keep your gun maintained, and watch for aluminum buildup just to be safe. As far as steel-cased ammo is concerned, there IS a genuine issue to be aware of. . . Some steel-cased ammo (and even some brass-cased ammo) has a lacquer coating on it which can potentially rub off and build up in your chamber (and maybe even your bore) causing all kinds of stickiness and maybe even overpressure (if it builds up in the bore). As long as you are vigilant about keeping your gun clean, maintained, and lubricated, you will be fine. Steel & aluminum-cased ammo might require just a little tiny bit more watchfulness and maintenance than brass-cased ammo does.

The next question goes to HK warranty when running non-brass-cased ammo. HK pistols are specifically designed, optimized, and marketed to run with quality, brass-cased ammo. Using non-brass-cased ammo won't void your warranty. But if your gun has issues running that stuff, HK will consider it to be outside the intended use of the weapon, and therefore will not help you resolve your issues. Same goes if you use your gun to hammer in staples on a barbed-wire fence-post. If it doesn't work well as a hammer, or if by using it as a hammer you break it, HK is going to say that it wasn't designed or sold to be used in that way, and that you are on your own. As long as whatever goes wrong with your pistol is not directly caused by something outside of it's intended use, you warranty is valid. Some people ask, "Well what if I take my pistol apart down to the last little component and then put it all back together again? Will that void my warranty?" The answer is no, it won't void your warranty as long as you didn't do anything to damage your pistol. It is intended to be field-stripped. It is not intended to be user-disassembled down to the last component. If by disassembling it down to the last component, you cause a failure, then again HK will consider it to be outside the intended use of the weapon. So the bottom line is that you can do anything you want with your gun. After all, it is yours. And HK doesn't mind at all. . . even if you use it to hammer staples. . . just don't ask HK to fix your bad if something goes wrong is all.

What about performance & reliability of non-brass-cased ammo in your HK? Well, brass cartridge cases have certain properties & characteristics, and your HK is designed & optimized around these. The gun is just a platform to enable the cartridge. The platform is designed to optimize the performance of brass cartridges. They certainly could have designed it to function very well with all types of cartridges, but then they would have had to make some trade-offs in other areas (tolerances & accuracy comes to mind). One of the many properties of brass is it's elasticity. When a cartridge is fired, the brass case stretches & expands to seal against the chamber walls so that all the exploding gases go to propelling the bullet down the bore. Then the brass cartridge case elastically springs back into shape so that it can be extracted from the chamber (all this at blinding speed). If it didn't spring back into shape, the gun wouldn't run. It would be a one-shot affair because the case would be stuck in the chamber after the explosion. The elasticity of ammo brass is different than the elasticity of aluminum and steel. Brass cases can be reloaded and re-used many times. Nobody reloads or re-uses aluminum or steel cartridge cases. Steel and aluminum cartridge cases are only good for one firing and then they are trash. They are cheap, and they are the mark of cheap, low-quality ammo. Better ammo uses better components. . . better powder, better primers, more uniform bullets, more uniform powder charges, etc., etc. If your HK seems to run reliably with cheap ammo, and that is what you want to use, it is not a problem at all, but performance & reliability may be lesser than with better ammo, in which case don't blame HK.
