yep, your trigger job does the same as mine just in a different way... and on a regular m98.
instead of putting tape on the sear pin, i sanded down the part of the rear bolt where the sear catches. (the right side of the space). then i polished the rear bolt, making the pull lighter and less friction.
next i put tape around the saftey to shorten the pull even more. then put tape around the pin in which the trigger pivots on.
then i put a replaced a spring with a lighter spring (stretched, but not too much).
my trigger pull is around 1.4 mm long.
i did all of this a year ago.
however i mine is more perminant which may be a good thing or a bad thing.
