In the main game, this weapon can only be obtained by beating the game once with an S rank on Standard or Hardcore (either of Leon or Claire's campaigns, no matter which) or by purchasing the "All In-game Rewards Unlock" DLC.
Its maximum magazine size is 15 and it can't be upgraded - since it features infinite ammo by default in the main game, using this weapon will default the player's rank to S akin to any other bonus weapons with infinite ammo feature.
In The Ghost Survivors, this weapon is featured in Robert Kendo's pre-determined loadout. The gun practically remains the same, although it features no infinite ammo unless the player is wearing the Cat Ears accessory.
