snubbiefan ,have not fired it yet .I am embarrassed to admit it but I can't get the original S&W boot grips off of it .I found the correct Allen wrench ,tried to loosen it , no dice . (The through bolt has a hex head ) It's almost as if someone had locktighted it . I really don't want to take it to a gunsmith to get the grips off .Any suggestions ? Afraid I'm going to round it off ,it's that tight .
