Mauser 1912/14 Development in .45ACP

Cool Forgotten Weapons merch! shop.forgottenweapons.com
Mauser did not limit their Model 1912 and 1912/14 pistols to just being chambered in 9mm - they also developed a number of prototypes in .45ACP. Today we have a series of three such prototypes showing the sequence of changes in the operating Mechanism used by Mauser. The first uses a friction lever with a buffer, the second is a revised version of friction delay, and the third uses the flapper-delaying system that became standard on the 9mm examples.

[@Roger_Stenning]

The "stacked springs" in the first model recoil buffer are a common feature in the automotive world. We call 'em "leaf springs", and they're normally bound together, and have been widely used in vehicle suspension systems before the advent of first, coil and shock suspension, and later, air suspension, systems. First time I've seen such a small implementation of them, however. Very neat :)

[@snootdingo9365]

Nice observation!

[@TheFanatical1]

It's always nice when you see physical principles overlap disciplines. The other famous example I can think of is that Hiram Maxim took what was basically a steam locomotive driving gear (instead of steam he uses the recoiling mass of the breech and barrel) and put it into his machine gun. Later it became a toggle-lock, but the principle is the same.

[@MrGrimsmith]

I seem to recall seeing some in a *very* old mechanical toy (possibly 1920s era) but I can't remember which one. Unfortunately we sold them on a number of years ago so I'm unable to check now. Still have some on the car in the garage though and they're so much easier to work on than modern shocks :)

[@henryrodgers7386]

Tiny little leaf springs like this are sometimes used on model vehicles, usually tanks, and small R/C trucks, like the kind they used to use as movie props. My father built models like that. Fascinating to see them in a PISTOL, of all things!

[@skepticalbadger]

@@TheFanatical1 Hang on. Maxim actually used a Winchester in his prototyping. It's far more likely that he took the toggle lock from that than it is that he independently came up with the idea based upon locomotives.

[@jrooney58]

Given that Mauser went through the same cycle of designs with 9 mm, I imagine that these designs were tried out simultaneously in 9 mm and .45 acp. It wouldn’t make sense for them to go back and try the same iterations in.45 after settling on the flapper system in 9 mm. Of course, given that these designs were being worked up around 1914, I imagine that they never were developed commercially because “War were declared” sometime around then.

[@jfess1911]

It has been possible to make things with high precision for a long time, but it took a huge amount of labor to do it. Make it slightly oversize and slowly machine, grind, or file the excess. To make those same parts quickly and cheaply was the challenge. I once saw an exhibition of "masterpiece clocks" that were made hundreds of years ago. The amount of labor that went into those things was astronomical (pun intended), but they were beautiful.

@@jonasstrzyz2469 i used to design guns on paper during boring school lessons. i was still learning how they work so most of the designs were absurdly complex or useless operating mechanisms. I later got in designing with fusion 360 and when the lockdown happened i started drawing at the computer. It was more of a thing done for fun than anything. Here in Italy you can't build your gun as freely as is done in the US. It didn't go anywhere and the design had problems with the drawing (i wasn't as good as i should have been with fusion 360). The handgun was supposed to be a sort of hudson H9 with the delaying system of the guns in this video (i had those three ideas on how to make it but designed only the first one), there were other interesting things i designed on that gun that i can write in an other comment if you would like to know.

@Martino I know this is going to sound strange, but I was also thinking of a design that is similar to this.

Please don't move to Illinois if you shoot. You will get ripped off and they will look for anything to take your guns. I transferred all my fírearms before they could come and 5ake them from me. I had a very large collection that I sold for $50.000 to a friend that loved my collection. I figured it took me 25 years to collect. I had a large collection of pocket pistols.

The fundamental fault of thoses flapper delayed systems is that they rely on actual springs for the flappers to close. Springs can break or remain clogged, so the flapper can remain open. Roller, lever or toggle delayed work purely thanks to geometry.

[@maxs.3238]

Gun Jesus took the wisdom and spread it via KZbin

[@tnekkc]

The 3rd delay is caused by the mechanical advantage of a steep angle is a high "gear ratio" to accelerate the flaps out of the way. This is slow because the force of the recoiling slide is presented with a heavy load. This would be like a truck starting up a steep hill in high gear. Acceleration would be slow.

[@jfess1911]

I would think that this mechanism would be sensitive to lubrication on the surfaces. With such shallow angles, a small increase in friction would have a big overall effect. I wonder if it is more reliable to increase the mass moved or its rate of acceleration by other means to make the system less sensitive to friction.

I only changed out the springs at the suggestion of my gun shop owner. Idk if it made a noticeable difference. Fortunately the sights have notches, so adjusting the rear notch was easy. Hopefully prices go down for 7.62x25 again. They used to be $17-$18 per box for PPU (without shipping). I like the PPU hollow points but have not gotten to test their expansion. There is also a website where you can buy grips that have a laser sight inside, or a magazine extension that increases by 4 rounds (expensive as heck though).
