There's is a fair amount of modification you can do just with a file, that will get rid of that "mass produced" look.
I have gone so far as to cut away the exposed part of the trigger and silver soldered a new external piece to the top section. It's been a while, but I believe when I did that, I just dropped it in the quench when I was done soldering, (red hot for hard silver solder) and then drew it back a little in the oven. However I did it, it's still working fine.
You could also probably get away with some bending by holding the bearing parts of the trigger in the vise, which would act as a heat sink, while you heat and bend the external part.
Good luck!
