I prefer the OEM trigger shape. The little hook on the end gives me a landmark,. It helps me know exactly where my finger is placed on the trigger. Not just that, but I prefer the plastic OEM trigger. I thought I wanted to replace my plastic trigger due to it "flexing". After I adjusted the post-travel, there was no more trigger flex feel when I fired. Since the trigger stops as soon as the pistol fires, I no longer had a tendency to keep pulling and "flex" the trigger. I adjusted the pre-travel as well, and got to like the trigger as is. Plus, the adjustment screws tend to stay put, and not loosen and back out in a plastic trigger. So no need for thread locker. The trigger bar pin is also tighter in the plastic trigger; an interference fit, so to speak. And finally, I am not yet quite ready to completely take my TSO down to the trigger replacement level. I really like this gun and it's too new to risk messing it up, lol. Because as yigal says, other triggers can look better, different colors and all.
