Fast Dear Tune up: "Now let?s take a look at the trigger paying particular attention to the sear. This is an area of concern because of the inherent trigger pull problem with the Fast Deer. It will not cure everything but it will surely help. Use a small wire brush (or a Dremel Tool with a wire brush if you have one) and clean off as much of the black chemical surface (it appears that not all of the trigger assy?s have this coating) on the sear face. Now, with a whet stone (or a jewelers file) and /or 600 grit wet/dry paper polish the sear face smooth. Take care not to create any beveled edges and that all edges are sharp and square. Next, wash out the trigger housing with mineral spirits or paint thinner to remove all of the gunk inside. Do a thorough job here using a small paint brush to work around inside it as best as possible. Don?t leave any brush bristles behind. Then, if available, blow out thoroughly with compressed air. If not, using a clean cloth, pat dry and set aside to dry for awhile by evaporation. (With care, it can be dried out with a hair drier) "
