M&P Stove Pipes & Ejector

[ekraus]

I just replaced the extractor (APEX) in my 40L with a 9MM KKM Barrel in it. I was having problems and getting a lot of

stove pipes. No matter what spring I had in it. Seems to have worked. But when I had the pistol apart i noticed the the ejector has

a pretty sharp edge on the front of it. It's worn. So I started looking for an ejector and I see 2 different ones. Did they change the ejector when they came out with the 2.0.

Did they change the sear block in the 2.0?
