Stoeger & Erma .22 'Luger' Schematics
 

First the Stoeger...Not sure who actually manufactured it, as the Stoeger name is the only mfg marking...

Not a 'real' Luger, but possibly of some use here... :thumbup:

Here's pics of a 'Stoeger .22 Luger' that sold on GA for $275... :rolleyes:

And here's the Erma .22 'Luger' schematic, for those [like me!] who don't do Facebook... :thumbup:

Thanks Rich, this helps to show folks that there are big differences between these .22 pistols. Not having paid much attention to the Stoeger design, I've noticed that it has many more internal parts than the Erma. More parts = more stuff to potentially go wrong, as a rule of thumb. But then again, the Ermas are able to achieve significant issues in operation, regardless of having fewer components to interact!

The Erma Ep- and La-22 have differences in trigger, trigger bar, sear and its housing and release, safety mechanism, and striker, and these parts are not interchangeable between models.

The Stoeger also has the gripframe and 'receiver' [barrel extension] integrated, and the barrel is fixed [pinned, not threaded]/does not recoil.

I would go out on a limb and guess that the integrated gripframe/'receiver' is also of Zinc alloy. Zamak perhaps???...

Ah! Here's a quote from the Wiki -

The first Stoeger Lugers were produced in 1969 with aluminum forging/machined frames (7075 T6 aluminum - tensile strength 82,000 p.s.i ). Beginning in 1980 the receiver material was changed to steel. One way to identify the frame type is by the safety selector markings. Steel frames will have a red and green painted indented spot while the aluminum frames will have raised lettering that says Fire or Safe. Use of a magnet is another way to identify the composition of the pistol frame.
