The drawing or order showing its elimination is in the Goertz and Sturgess book,IIRC; but I have seen it in the original form somewhere.

Don,

I have their book,

Do you have the chapter and page number?

Thanks!!

4 Scale,

You assume that the specs are correct for a Luger.

Probably (most likely) not.

Hot ammo causes breach block slap in Lugers, eventually beating the pistol to destruction.

Glad to hear that your purchase has been a success for you in your weapons.....always a nice feeling to make a good choice!! The price was certainly attractive, and would be popular for 9mm "buzz gun" owners.

rhuff,

PMC ammo does not have steel cases and they have advanced quality control.

I've shot quite a bit of their ammo over the years, but have experienced some jamming in my Lugers.

Factory documents on the subject did survive.

Portuguese 5012m also has no step.

Vlim,

A hand reamer would seem to indicate a field modification, not a change in factory barrel design modification.

Your thoughts?

Kurusu,

Did he purchase his Luger factory new?

Thanks!!

David,

Is 15 rounds a realistic test set?

On the other hand, if it's only a shooter and not a collector grade Luger, perhaps your reasoning is correct!

Oh, I don't assume that. I've had issues with Russian quality in the past in non-firearm areas which makes me wary. I appreciate David sharing his results and wish him well with this ammo but I don't plan to use it myself.

Both options were developed. The hand reamer was meant for modifications of existing pistols, while the removal of the step in new pistols was just a minor change in production steps.

The hand reamer was also used to test the effectiveness of the modification.

About steel cases, I think the old lacquer coating did more harm than the steel case itself.

It was on service before he purchased it. And we didn't ream the chambers.

I don't pretend to know the square root of eff all about this subject, but two pages and I have yet to hear any concrete reason as to why the OP's ammo would be harmful to a Luger, or any other gun. All I'm reading here is FUD - come on guys, we can do better than this.

Zorba,

Breach block slap.

I do believe Zorba meant why that particular ammo would cause harm.
We have most all seen evidence of "toggle slap", but have no idea whether a few or a few hundred rounds of "hot ammo" caused it- or thousands of rounds of "normal" 9mm P; or a weak mainspring caused the any problem

You and others "assume" it will cause "problems", but without any data or experience with the same ammo to back it up.
Without evidence- like published velocity data, or first hand experience; it is all conjecture.
Everyone has said- "maybe, could, might, possible"; which sounds like "nervous Nellies" to me.

JMHO.

[Zorba]

Yep.

[DavidJayUden]

I'll take both the Russian stuff and some Winchester white box along with a roll of masking tape the next time I go to the range. It will be very unscientific but I'll try to determine if one or the other flattens the tape more violently. 2 or 3 layers of tape across the contact points on the back?

[ithacaartist]

One layer should do it.

My view on "toggle slap". Toggle slap is part of the Luger operation as much as the mark on the VIS of a 1911. It will occur with any military specs ammo. The amount of firing done with the pistol will increase the marked area without fail. The truth is, most Lugers were very seldom fired, even during the war, pistols were mostly a badge of rank or a last resort weapon. Any Luger that has shot more than 2k rounds will have evidence of "toggle slap". Either you shoot it or you don't.

Of course you can carefully tailor loads that will not do that (around 850 fps with a 124gr bullet will do that, and the pistol will cycle), but they be will well below any militay specs load performance. And the Luger was designed as a militay pistol from the start even those in .30 caliber.

Context kinda comes to mind.

War weapons, used in war, the longevity of the weapon is not a primary goal, make them cheaply and put as many into your side's hands as possible. Ammo kinda the same to me, steel is easier to procure than brass.........hard on chambers, but............who cares in events like that; as long as it goes bang, what's a little toggle slap or accelerated wear among friends? That same thought process even pertains to the poor individuals behind them, after all, everything or anyone is certainly replaceable in some circles.

Everyone has their own thoughts on all of this Luger pistol, Luger ammo, springs, etc. Some think as long as it goes bang, we don't care beyond that. Some that want to preserve what they have, try to use methods that will keep the pistol intact for a while. All pistols break, does not seem logical to me(my own opinion surely) that I should go looking for trouble by ignoring what the pistol is telling me, sorta speak.

Barrel steel is relatively soft, is cartridge steel harder or softer?. Perhaps an exercise for the internet google types huh? for those do it yourselfers, rub a piece of cartridge brass on a steel barrel(hopefully a discarded barrel, not your 1900). Then rub a piece of steel cartridge onto the barrel; each until you give up on the possible learning(if any) concept. One might consider using the case sharp mouth as the contact to the barrel, might take longer, smooth on smooth; but to each their own process. Could be just a silly Rick W. snipe hunt.......... :-) Never done it myself, but I can imagine...........and that is still a freedom currently.

I shoot Lugers a fair amount, even the ones in stainless that everyone bad mouths, all I can say is that my Lugers, stainless and blue are getting the best I can give them. Not making many anymore, I can see the time where my lamp for these pistols will eventually go out...........but hopefully my Lugers will still function and offer their mystique to the next user says the non collector.

As usual............to each their own..............maybe one of our greatest freedoms.
