Fuzzy, the new PC lock can be actuated through manipulation, and requires that key to take it off. Not a good idea for a "Serious" shotgun, and a PITA for a sporting shotgun.
In general, QC has gone downhill for Remington. The safety is just part of it, interior parts show more slop and roughness, the PC "Dimples" in the magazine are another questionable item, and Remington has a rep for lousy after purchase and warrenty work.
Even with all this, an 870 is a good shotgun, but they used to be great.....
