No, they're not. My L2 triggers are fine, just like new. My R2s have very weak resistance to the spring, almost like it has slipped or something. |
Then you mean mushier.
I just stripped a PS3 controller down to the circuit board.
There's a single, fine gauge spring responsible for the tension in the shoulder trigger buttons. It's very thin, but there is no way it can "slip" based on the way the controller is assembled. A solid steel roll pin goes straight through the loop of the spring (it's a single coil) and the shoulder buttons.
The spring tension could be adjusted by bending the OEM spring beyond 90 degrees. If you really wanted heavier triggers, it wouldn't be too tough to make a single coil spring out of heavier wire, which... I may actually try now that I have a disassembled controller.
(just made a pair of trigger springs out of 17 gauge nickel wound guitar string; spring tension is noticeably greater. could go as high as 20 gauge, but don't have any 20 gauge G strings at the moment. I'd do this to all my controllers if it weren't such a pain to put them back together.)
