Currently trying to fit a trigger in a Tisas. Factory slot appears to be oversized...

Trigger on the Tisas was fine, other than it had vertical up and down.

Factory trigger measures .9173 tall, .2375 wide, .229 bow

Trying to fit an Ed Brown
.231 bow
.920 tall
.245 wide

The Ed Brown just drops in.

Anyone got a line on a trigger that it even taller yet?

It doesn't really help except to eliminate them but I have an unmolested Harrison trigger because I'm waiting on other parts.  It's also 0.920 tall.

I used a Wilson Ultralight Match trigger in mine. It required fitting.

Thanks guys I appreciate the replies. First experience I ever had with fitting one of these.

I was pretty shocked that the Ed Brown was that much larger and it was still a bit looser than I'd expect.

I think I may have gotten this solved. I ended up peening on 4 spots on the sides of the shoe towards the rear.

It most definitely required vertical fitting after that, and multiple rounds of sharpie and sanding.

Think this is gonna turn out like I hoped.

I use a diamond stone on mine, it cuts aluminum real quick and leaves a pretty smooth finish.
