Are there any flat triggers for a P239 other than the P220/p239 trigger from Armory Craft? I tried one but it didn't fit. The AC support rep stated there are a few P239s that dont fit their trigger. Mine is a .40 cal DA/SA. Any other options I can try? And any markings on the gun that would tell me what should and should not fit? Thanks!

Gray Guns?

I asked Grayuns and was told they dont make a trigger for the p239
