Toggle not locking at all anymore?

[4 Scale]

It's good you solved the hold open problem. On your ejection and cycle issue, IMO your best course is to wait for PPU to become available or somehow secure hand loads that are known to operate .30 Luger actions properly.

Sometimes folks will change out the button on the side of the magazine because of wear somewhere in the pistol. When I think of magazine height in the pistol kinda refers me to the notch in the magazine or the magazine latch itself, this also refers me to feeding height of cartridges.

The little button as you found out effects the hold open height when the mag is empty. The parameters above can enter into the operation of holdopen as well. I think the little leaf spring's main duty is to hold the holdopen itself down into the frame, until it is overpowered by the magazine. Recoil bounce should not effect the leaf spring's capability or you will get premature stoppages.

New oem buttons for magazines are usually available. Probably cost more than the new after market mag you bought though. I once got a Luger magazine that featured a portion of a bridge spike for the magazine button. The previous owner shaped it nicely and it worked. Have to admire using what you have sometimes, rather than throw money at things, all in the eye of the beholder.

I find the Italian magazines of nice quality, works fine in my Lugers; and mine are not all original anymore, shows the flexibility of their product I think.

You took some measurements, now you know how much bigger the button ought to be to work in your current environment. Sometimes tape can be wrapped around the outer edge, and then measured when things begin to jive.

Ammo is only one parameter of the function equasion. Easy to try I reckon and sometimes does the trick. I once had a previously owned Luger that I could barely pull the toggle train out of the receiver, the forks were twisted big time. A bit of a pain in the neck back then, but nowadays some guys have jigs for such work.

Rick, thanks for the words, I'm going to have to move through this one step at a time. Initally I got some Fiorcchi Soft Tips, the armorer corrected that with me (good guys) and I now have some 7.65 Luger FMJs but the grain is the same, don't think that will solve much really. The Soft Tips did get hung up (as seen in previous photos) but the fact that the toggle isn't left up and open after the last round; each round as I am shooting one at a time, tells me there is more going on here. Bit of research I did had a kit or "service pack" at Wolff springs that was not that expensive that replaces all the springs in the gun. Might get after the leaf spring you mentioned above.

Went to range today (Military Base I live near) and it was closed (?) when normally open on Sundays, closed tomorrow too. Hope to shoot next weekend. Just to put more rounds through the gun--bring it out of hibernation (wishful thinking but improbable). Oh well, life is a marathon, not a sprint. I'll get it sorted.

Oh and my wife said "no shooting rounds into the pool!!?" I thought it was a reasonable way to test the gun? Keep the rounds from harming anyone! Thoughts?

Yep, the PPU is the least involved method of repair. But can't find any words or data on why there is none in the country. If the PPU doesn't help then possibly the spring is too strong? Maybe originally for a 9mm barrel?

There is PPU "in the country". You have been told that it is produced and imported in batches, and gets largely sold out between "batches".

If you want a box or three for $35 each plus $20 ground shipping, I can get it for you.

You just did not sound like you wanted to spend that- but then I recall you are in California, and ammo must go to an ffl dealer, so then the cost goes up even more.

So I guess you just must be patient.
I do not recommend firing into your pool either.

DonVoigt, was kidding on the pool part. I live in a gated subdivision, people would lose their minds!! HOA would not be happy.
Am in Nevada so not so many restrictions here. Patience I have, generally. Let me see what the FMJs do, get those run through the gun and see. Oddly, the second time I took the gun out, older mag, the gun was ejecting and hold back working when I cupped my left hand and applied pressure to base of mag (slight rise). Not the case with the new Mec-Gar Mag that does provide hold back when toggle is pulled by hand? I need another day at the range to tinker with it some more.

So PPU bought and inbound. Quick look at the
Fiocchi specs:
Muzzle Velocity is 1190 FPS Muzzle Energy is 290 ft Lbs

PPU specs:
Muzzle Velocity is 1280 FPS Muzzle Energy is 413 ft Lbs

I tried to do some research and see if there was any error in these numbers, the Fiocchi Muzzle Energy varied a bit, but less than 5%

That is a huge delta in muzzle energy so that would explain why the PPU is better at working the toggle and cycling the next round. But is this TOO MUCH energy?
Folks have had good luck with this ammo at 7.65 and the Luger?

How does PPU get such a bigger energy in the same casing as the Fiocchi?
