Have over 200 rounds through my 43X and the very aggressive ridge design on the trigger shoe is eating my finger up. Would like to ONLY REPLACE the trigger shoe with a flat face trigger shoe. Question. Does only replacing the trigger shoe...not replacing any other internal component of the handgun...fall under the realm of "never modify a carry handgun" legal nightmare? Would I just be better off using a piece of sandpaper and smoothing down the trigger shoe ridges? Thank you in advance.
