The Walther PP is available in two chamberings (.32 ACP or .380 ACP) and two finish (matte black steel or matte-finished stainless steel) options, for a total of four distinct models.

Power is supplied by a single 5V USB-C port, and the PP-1 features just a single 3.5-millimeter audio jack for connecting it to either active or passive speakers that require an additional amplifier.
