Walther PP
The Walther PP (German for Polizeipistole, literally "police pistol") was a semi-automatic pistol used on Earth by civilians and the police.  

In the Dixon Hill series of holographic programs, Felix Leech, a hit man for Cyrus Redblock, owned a stainless steel Walther PP with pearl grips. This weapon was fired by Leech, wounding Whalen in the process. ()

In the holoprogram Julian Bashir, Secret Agent, the scientist Doctor Hippocrates Noah and the secret agent Julian Bashir were armed with the Walther PPK, a variant of the Walther PP. Dr. Noah's gun was nickel-plated and Bashir's gun was one of many hand-held weapons he kept stored, ready for use, in his apartment's armory. ()
