I have a PMACA standard (no provison for KIDD rear tang) that has a Tactical Innovations trigger assembly, and although it is very much a copy of the OEM Ruger trigger assembly, there are differences in the dimensions between the two.
I noticed that it "touched" (kind of like a shimmed effect) the delrin inverted
L shape (a PMACA staple) atop the pistol grip slightly, and when I tightened the action screw, the whole assembly became rock solid with the added leverage.
I originally thought of relieving the anomaly when I first noticed it but decided against it---turned out I was right about my decision.
Read somewhere of a guy relieving the aforesaid inverted
L delrin, as he had issues with his action not sitting right. Forgot what trigger assembly he had though, perhaps an aftermarket one like mine.
Perhaps I got lucky with mine the combination was just right.
