dager's right, don't cut it.
You can get the same results by wrapping tape, aluminum, or shrink wrap around the pin in the trigger frame that the sear rests on--then all you'll need to do is polish the sear/striker. Do that with a felt wheel and some Mothers Mag Polish(course a soft towel, lots of elbow grease, and Mothers Mag Polish will do the same job over a longer period of time)...
