Black-Max 380 Locktight is what has been recommended by others. I did one on the hook of an 80 year-old Nitro Special and it is still holding up nicely, I used 50/50 solder and filled the tubes with water so as not to overheat anything. And HOmeless Joe, only an abject idiot subjects a gun to the average gunsmith for refitting. The soldered shim is the least intrusive of all remedies and does not harm the integrity of the hook as some guy filing a dovetail and inserting a strip of metal. Chopperlump
