I have Apex, Overwatch TAC and Falx, and Tango Down Vickers triggers, all are 3/8" wide, as is the OEM Glock trigger -- how the face is shaped then is what makes the difference. The TAC has only a slight radius on the edges so it feels widest, the Apex softens the edges a bit more, and the Falx will definitely feel narrowest -- its edges are most rounded, so the center contact patch is less. Personally I liked the Apex and have standardized on them, just haven't gotten around to selling the rest. If you're interested in trying any of the others shoot me a PM.
