Star Model S
S Series pistols are very small copies of the M and P series in .380 ACP or .32. They are all made of steel, and have the same basic dimensions. They were produced for many decades, resulting in a number of sub-variants with mostly minor internal changes, but finding correct replacement parts can be difficult. Some variants are described by a model suffix change, ie: SI, SM, but some are not. Besides widespread use with police forces throught the world, a large number were used in WWII. The Luftwaffe in particular used a large number. These will not have nazi proof marks as they were accepted into service with only spanish marks, the only small arm not german proofed in WWII.
