Grip Screws
Before anybody gets the idea that Wilson, or any other gun manufacturer or builder is supplying sub-standard parts, please bear in mind that they didn't make the screws in question. Those parts were supplied by a vendor whose manufacturing process is subject to the same nuances of any other mass-produced part. Some lots turn out fine...Others don't. The next batch of screws may well be stronger than Superman's cape...and the one after that as brittle as glass, followed by another that's as soft as butter. Since wilson Combat, or any other maker/builder can't afford to take the time to test each part that they have in their inventory...sometimes a bad part gets passed along. Luck of the draw.
No current manufacturer that I'm aware of makes their own grip screws or sears or disconnects or springs or pins or....Well, you see my point. Those parts are supplied by the lowest bidder, with all that is implied. Welcome to the 21st century.
If you can get a small drill bit to bite into the screw shaft without buggering up the bushing, it'll probably spin it out, since it doesn't thread into a blind hole and bottom out, it's probably not very tight. You may be able to turn it through and out with an ice pick. Might take some time...Put on a pot of coffee and enjoy fixin' it yourself.
