The Cayo Perico Heist introduced two new weapons for players to acquire in GTA Online: the Perico Pistol and the Combat Shotgun.
This guide will walk you through the steps to obtain these weapons. To get the Perico Pistol, you first need to get a special key during a random event and then use that key during the Cayo Perico Heist finale. You'll also get the Combat Shotgun during the heist finale, but it will simply spawn for you (no key requirement).
Once you've obtained the weapons in the heist finale, you will get to keep the Perico Pistol for free, but you'll have to purchase the Combat Shotgun from the Ammu-Nation.
Perico Pistol
For the Perico Pistol, you need to acquire a 'Small Key' obtainable only through a random event that triggers only at certain locations. In this guide, we will show all the possible event locations. In this random event, you will come across a passed out guard. You can interact with him to search him for the 'Small Key.'
The key is used in El Rubio's office during the Cayo Perico heist finale to obtain the pistol. Once you acquire the weapon once, it will be available to purchase at the nearest Ammu-Nation.
Random Event Locations
You will see a blue dot appear at the locations shown below indicating a random event, just like any other random event in GTA Online.
