This one was very tight but I've never had those grips off so not sure why 3 came out fine and one didn't. Thanks for the help guys! I'll see how it goes...Another good argument for using slotted head screws, like Browning did...
Also, if your grip screws are so tight, something isn't right.
EZ out, drill, grinder, files, all can be used. Another trick is grinding down the next size larger allen wrench, (bit by bit) until it can be driven into the buggered up screw head. (this is key, if you grind it small enough that it "fits" it will slip and you go nowhere, it has to be tight to grip in a rounded off hole.)
Good Luck.
The last one out will always be the tightest. You've relieved all the tension by removing the other screws which means that the one left in will be holding more tension than normal.The other 3 came out fine and of course the last one gets jacked up.
This works fine...unless it is the screw that is stripped instead of the Allen wrench.Another thing, grind the ends of the allen wrench past any "rounding".
I thought Ed Brown 1911s used Torx grip screws. If so, it's no wonder you stripped the Allen wrench.
