Apex SD Polymer Action Enhancement Trigger

[axxiom]

I have an older SW9F and I've installed the Apex Spring Kit with great results. Now I'm thinking about replacing the stock trigger with the Apex "SD Polymer Action Enhancement Trigger". Does anyone have experience with this Apex trigger replacement on your Sigma (either 9mm or 40)? In particular, I'm curious about whether you had to file down the trigger a bit in order to get a good fit on your Sigma.

not sure how it fits into a sigma but I did drop one onto a SDVE9 and did have to file a very small amount off of the back side which I did after it was in,Perfect fit and no problems.If the dimensions are the same on the sigma you should have no problems,But to be sure give Apex a call their customer service is top notch
