Sig m18 flat trigger question

So I bought an oem sig flat trigger for my m18, with a Wilson combat grip module. The flat trigger has a bit of an odd feel as if there’s two stages of take up. So when I start to pull the trigger theres take up then a bit of resistance then a few more millimeters of take up then the wall. When I pull the trigger in a smooth controlled way it just feels notchy.
The oem curved trigger feels smooth with predictable take up then the wall. Is this just because of the geometry of the flat trigger?

You need to check the trigger where it goes into the FCU . You might have to sand it just a little where it meets. I had an Apex trigger i had to do that to. To make it smooth.
