Just an update. S&W was not interested in putting the PC sear in a 2.0, in a very vague way the customer service person told me it was for the 1.0 version and basically they were no longer doing it.
If what I read is true about the 1.0 going away this will leave us zero options from S&W for any improvements in the trigger.
There are a lot of options out there for the 2.0, everything from a 2.5 lb trigger to stock to all the kit options from Apex. My goal was to have the triggers in my PC 45 and this 2.0 9mm as similar as possible, I settled on just putting in the Apex sear after watching their video. They showed an approximate 2 lb. reduction in trigger pull weight which would put it very close to where I was looking to be.
My 2.0 has the thumb safety which turned out to be zero issue in the sear install. After watching the video I went after it and I must say the install was very straight forward and quick. The only item you need to pay attention to is the sear pin head, it has I believe three flats on the head. That pin is pushed out from right to left as viewed from the rear. Because of the thumb safety lever it needs to be positioned so the flats on the pin line up with the thumb lever. Very easy to do just be aware.
Bottom line is I have exactly what I was hoping for with just over 4lb smooth crisp trigger, reset is also much improved. Looking forward to my next range day.
