Do you have the problem with every magazine? You might want to check your mag springs as well.
I have two Mustangs, one with a polished ramp, and one without. Both feed Golden Sabers without problems. But I did have some issues with an older mag in the past that affected hollowpoints (Federal). The heavier springs from Wolff solved the problem.

What kind of grips are those on the pocketlite?
