Para lda barrel bed/frame wear ?

[Sitcomdad83]

Not a 1911 expert but never seen this wear on frame barrel bed area before. Is the barrel "seating " on frame before lug does? Could The link be wrong size? Should I worry? Hope the pic shows that the factory finish is still very thick on back edge of frame makes me think barrel isn't retracting fully rearward. The slide lug recesses and upper barrel lugs aren't rounded off. No idea of round count or if link been changed. Fires reliably and passes function test and the slidestop link test.
