I hacked a smooth trigger onto my G36 years ago, so doing it to my 43 was no big deal.
Buy a spare 17 trigger bar. Using a small punch, tap on the pin holding the trigger shoe enough that it leaves a pimple on the blind side of the trigger. Then, using a straight pin chucked into a pin vise push through the pimple to drive the pin out enough to grab it with a pair of needle nose pliers. Do the same to the other trigger bar, swap the shoes and reinsert the pin. Done.
Takes ten minutes.
