Anyone ever do this to get 1/4-1/2 lb drop in trigger pull? Or know what it's doing internally?
most times, many parts on a 1911 needs to be "fitted" which in a way means "worked on" to make it fit.
but you need to be extra careful, too much "work" might ruin the gun.
i bought honing stones specific to the 1911 trigger, and sear...i'd like to get a sear jig, someday, but i ain't pushing that as a top priority.
next, if you'd like to work on your 1911, then i suggest buying a cheaper one, like a Tisas, or Girsan, or the Remington R1, maybe even a Dan Daley, i think they all are under the $500 price point at some gun stores.
practice just doing a full tear down and reassembly, many, many times.
watch video, "gun blue" that older gent is a very well accomplished armorer, and knows his stuff.
there are others as well.
then you can start buying "sear jigs" and "honing stones", and have at it, on the cheaper 1911's.
as it stands now, all my 1911's are above the $1,200 price point, and i ain't about to work on them.
i "might" buy another cheaper 1911, and try myself, since i already have some of the tools required.
