I have a couple of handguns where the grip screws loosen up after a fun afternoon at the range. I know I can use Loktite, but I'm not sure which color is best to use. I'm pretty sure I don't want the super-duper, heavy-duty permanent stuff, though.
Also, is there an alternative to Loktite? I seem to recall there might be, but I'm old and married, so my memory ain't so good anymore.
