I think the difference between PS3 and 360 here is understandable, as on the PS3 just about every button (including, ironically, the d-pad) is analog, though they have a software setting to behave as digital. Hence all buttons have some travel. On the 360, the 'R1' button hardly has any travel. With the PS3 R2 button being a little too low compared to how you hold the controller, it's not as comfortable to use, at least for me. Should they ever do a redesign, I think there is some room for improvement in that department (the R2 button also sticks out too much, when you set the controller down or lean it on something it's too easily pressed)
So yes, it's typically the R1 button on the PS3. At least in the games that I've played, Resistance, Warhawk and Uncharted.
