Did a search and the last thread about MCX and after market triggers was in the DEC/JAN time frame and the recall was still being worked out.
It's May now and I am looking to buy an aftermarket trigger for my MCX with the G2 carrier group.
Talked to Sig Customer Service rep and they if I got a Geissele they could send an additional part to make it work. Other triggers would require sending the gun in and they would make it work.
Asked Geissele about it and got back this:
---------------------------------------------------------------------------------------
Thank you for contacting us. In regards to our stance on our triggers in the MPX / MCX, as the industry grows, there are more and more AR variants out there that accept AR15 fire control groups. Each one is different and though we would like to, we have not tested our AR15 triggers with any of them. What we know about our triggers in the MPX / MCX we have learned from feedback from our customers. From the beginning, our customer service representatives have explicitly told people that we have not had any experience with our trigger in the MPX/MCX. We have stated that forum users have claimed to have success but we cannot confirm their success. We have never strayed from this and have never confirmed our trigger work in those platforms, and have always maintained that our triggers were designed to function with a mil-spec M4 carbine. With that said, the MPX has a very fast action, which is why the MPX ships with the trigger bridge, to protect the fire control group from the action. The MPX was designed to be used with the trigger bridge, our triggers were designed to be used with AR15 rifles using mil-spec components. While the MPX and MCX combination will work for a while, it will eventually fail. We want to be clear with our customers on this, and also have them know that we are working on specific triggers for both variants.
Going forward, rebuild kits for our AR15 triggers installed in both platforms will be available. The SSA- MPX / MCX trigger groups are currently in development and will incorporate a trigger bridge to alleviate the current issues. It is slated for release in 2017. Unfortunately the SSA-MPX / MCX triggers are still in development and the price has yet to be determined.
Thank you,
Nick

The Geissele note is discouraging.
I am hoping someone has some experience with an aftermarket trigger and a G2 carrier group.
THanks in advance.
