Just to add more trouble, some pistols will simply be marked "Super," with no letter codes.These are the Super (linkless, quick-takedown lever) versions of a number of models.
Some will simply need to be identified by looking at photos.
Check the model A and B pages for the closest match and read the descriptions.
Some older pistols will have no model number on the butt.
This used to be rare, but is increasingly common as old stocks are cleared out.
Model names are all too frequently a source of confusion for Star pistols. The right place to find all older Star pistol model numbers is on the butt, as seen in the illustrations below and photo to the right.
Especially for the older pistols, there are just a few tips you need to know to almost always find the correct model of your gun. On the flat plate on the bottom of the gun, just rear of where the magazine is inserted, look for a letter, set of letters or a word.
The chart to the right delineates the differences between some of the more confusingly similar pistols, and what I know of some of the suffix codes.
Models A and B, for example, are confusingly similar, but are (apparently) differentiated by caliber. Some are not at all clear, but the ones I know are listed here.
Newer pistols have a model name or number, sometimes with a type suffix, clearly on the sides of the gun. "Firestar Plus") are on the slide and any listed model numbers are on the right side of the frame above the grip panels. The Megastar, for example, is the Model 50, but is [more or less] invariably sold as the "Model Megastar." All the modern pistols have model numbers instead of letters, starting with 28.
