Earlier this year I purchased a DW 357 mag and am very happy with it.  Rear sight was original and the gun is in excellent shape.
Last week I noticed that the rear sight would wobble back and forth.  I have read about this on this sight and the DW Forum.  Here's my question.  Is there a fix other than replacing the sight.  Why...first, other than DW, I cannot find a rear sight to fit.  Seems all info points to discontinued.  Second...I am cheap and like to fix things rather than replace...So, who has a fix for this wobble
