Does anyone have a source for a good gunsmithing video for the 1911? I just bought the Clark Customizing the 1911, and was dissapointed. It was more of an infomercial on their services than a how to video. This was surprising to me because their Trigger Job video was exceptional enough for me to do a fine job on an N frame. I'm not looking for machine work info, just a smoothing and polishing pointer.
