The tool Kimber supplies is crap... and everyone seems to make it alot more complicated than it is.
Here's the method I use...
Has anybody seen this new tool to use instead of the little pin they supply? Think I will order one. Sells for around 10.00 plus shipping on Ebay. Watch the video, pretty neat at least I thought so!
follow his directions, and it is very easy!
As he says in the video, place the end of the sping at 5 0'clock when reassembling, and it will work smoothly.
