I just did a full respring on my S&W 686 and I personally will never do it again. There is one little devil spring that was a monstrous pain right in the butt. I finally had to take it to a smith to fit it for me. As for all of my other handguns, practically all of them have been done piecemeal while changing them for different weight etc. Not a one of them is even close to 2K now, so 10K is a long way off.
