Well,
the spring is what pushes the retainer to the rear, without it it would not lock in, any "extra" pressure =more wear.

I never said it was the only factor, only that the spring is much stronger than needed and a big factor in this type of wear, IMO.

Lubrication is always good; and yes, in "normal" operation the guide should not contact the rear of the frame.

It would take a Lot of shooting and/or firing higher power loads to do this.

It is not a really common failure, again JMHO.
