I never really thought about it. I guess I do treat the trigger like a two stage. I'll preface this though by saying that I do so with just about all guns I shoot with over a 3.5lb trigger. By this I mean I take up the slack to the friction point, clean up my sightpicture, and then break the shot. During recoil, I will ride the trigger to reset and no further, and send my next shot if needed. If I don't finger comes off the trigger and gets indexed on the frame. After enough trigger time, it's rather easy on a Glock which has a rather tangible reset. It was harder on my M&P which had a very weak reset similar to an M9 until I changed the sear and trigger out with the Apex ones. Now it is much easier to feel the reset. Having started with various DA/SA pistols, I greatly prefer the consistency of a striker pistol.
With practice you can speed this up or slow it down. You’ll be just as fast and get better hits than slapping the trigger
