Does anyone make a universal trigger overtravel stop?

I've got a few milsurps I don't want to modify.

There are universal trigger shoes used on paintball guns.

Is there a version that allows an overtravel stop?

Yes, if that width will work for you Palmer’s pursuit shop used to sell those exact shoes with a 4x40 nylon tipped set screw in them.
I worked there back in the early 2000’s and we included them on a lot of our markers. There are likely other places you can find the same thing.
