^^ This. Harrison triggers are excellent. I have replaced all of my 1911 triggers with the Harrison short triggers.Harrison Custom also carries short (and long, and medium) solid (no overtravel adjustment) triggers...good stuff.
Available in black or silver.
I wouldn't say "All the short triggers at Brownells had the hole in the trigger face for a trigger stop screw" given that Brownell's stocks the Harrison among others. I bought a black one there to match a painted 1911 and maybe look a little more industrial. Maybe not catch the eye like the aluminum. Maybe not but it suits me. I've also bought short triggers with serrated faces and file adjustment. I shoeshine a little bit to make the outside serrations less prominent and leave the center serrations proud to stabilize the finger pad mostly.The face of the trigger shoe is smooth; free from serrations and holes for the over-travel screw that can chafe and abrade your trigger finger during long training sessions.
The fixed over-travel stop is permanently locked in place so it can't creep in and render your pistol inoperative in an emergency. The initial adjustment to the over-travel stop is made by filing and re-testing until the correct amount of over-travel is achieved.
That's exactly how Harrison triggers are set up.
It is a non-adjustable post that is threaded in. The instructions that come with them say to file it for adjustment.Harrison triggers have a set screw from the back.
