“Erma” is a contraction of Erfurter Maschinen und Werkzeugfabrik, later known as Erfurter Maschinenfabrik B Geipel GmbH., or simply Erma-Werke, originally located in Erfurt, Germany.  The company was known early-on for making a .22 conversion for the P-08 Parabellum pistol, and during World War II they made the famous MP38 and MP40 submachine guns.  After the war and the division of Germany, the company was reconstituted in Munich-Dachau.

All the Erma “Luger” pistols had an unlocked “blow-back” action.  In the 50s, the first example of the .22 long rifle auto concept was embodied in a pistol by Erma called the “Old Model.”  These are rarely encountered today. Somewhere around 1964 the first Luger-styled pistol, the LA-22 was produced.  Its construction was mostly of cast Zamak.  Aside from the barrel liner, breech block, and internals of steel, all else was made from this zinc alloy.

Soon after the LA-22, Production of the EP- and ET-22’s began.  Their actions were changed slightly--presumably to be more dependable, but just as likely to save manufacturing costs.  Differences include changes to the trigger and sear systems and a re-design of the safety.  The ET-22's action is identical to the EP-22's, but it has a longer barrel and a walnut fore-stock.

The zinc alloy guns were phased out at the end of the 60's and replaced by the totally re-designed KGP-69, in .22 long rifle, which was scaled down about 75% from its predecessors which had mimicked the dimensions and weight of the original Parabellum pistol.  The KGP-68 and -68A were scaled to about 2/3 size of the P.08 Luger and came in .380 and .32 auto --they differ only in caliber.  The KGP series is more true to the lines of the original Lugers, despite the smaller scale.  They even have a tiny hold-open system.  Beeman imported the KGP series, re-branded as the Beeman MP-08, through the mid- to-late 80's, until the end of production.  The Erma’s factory plastic grips were replaced by artisan-crafted rosewood grips, and the finish of the Beemans seems finer, smoother, and more attentive to detail.  A set screw to limit trigger travel is installed on some examples of the "P-08", which is the .22 long rifle version.  Erma-Werke went bankrupt in 1997.

For a brief time the Spanish company Echasa (Echave y Arizmendi) made a copy of the EP-22, which was known as the Lur Panzer.  It is very scarce today.

I bought the gun illustrated here at the Austin gun show for a friend who had asked me to keep an eye out for one that was reasonably priced.  There wasn’t much information available online about the gun, and it took us a long time to find instructions for field stripping it, so I thought folks might find it useful if I were to publish instructions and photographs.  We could never get the gun to function properly, even after a complete cleaning and lubrication, and my friend quickly sold it.
