How do you hold Ps4 controllers?

I have a question, how do you hold your Ps4 controller at Fortnite. So I mean how do you use L2 and R2, do you do that with the ring finger or do you use L1 and L2 with the middle finger?

With the index finger

So I'm not playing Fortnite but I would recommend using the left index fingers L2 and L1. On the right the same with the right index fingers R2 and R1. This gives you more focus and you don't have to use up your middle finger strength. If you buy an add-on for the rear controller, you can also operate it with your middle finger.

Thank you!
