grip screw seized

New screws are available on ebay. One possibility: applying a little bit kroil on both ends of one screw, waiting 72 hours, the edge of a 1c coin (soft, damaging the 1c coin in worst case) could be used a screwdriver on it. If this works on one side, apply the same procedure on the other side.

I second what Alvin said. Another thing that usually helps is to tap the screw after you apply the Kroil, this breaks the crud and makes the Kroil penetrate better. The easiest way to do that is to put a screwdriver bit in the slot and tap it with a hammer. Quick, firm taps with a small gunsmith hammer works well for this. Metal to metal contact works best, tapping the plastic handle on a screwdriver may not work at all.

You can bend the frame if you tap too hard, so you may want to use some kind of support in the mag well. A piece of scrap steel put in the vise will usually work as a makeshift "anvil" for this.
