George, welcome to the forum. I also have an ERMA, a KPG68a (32cal), that is a sweet little pocket 'Luger' that I love to shoot. Several folks on this forum own ERMAs. Cool little guns.
Review the FAQ section as it is really a Luger primer and many of your questions will be answered. As you already experienced, once you buy a Luger, or even the toggle action look-a-likes, you will want more. These things are addictive.
Keep us posted.
