When I was a new shooter I was convinced Glocks were unshootable because of the grip.
I ended up with a G3 G19 because a friend needed to sell it. Right around that time I got into USPSA and learned how to actually shoot. I ended up selling my CZ75 and buying another G19 so I could have separate carry and comp guns.
It's easy to fall into the trap of "OMG this gun didn't shoot perfect" when you're a new shooter. The reality is once you put in the time and practice you'll shoot anything better than you shoot that "natural pointer" as a novice.
With all that said, a G43 is not an easy gun to shoot. I don't have much time with a G48. Neither would be my first choice for an inexperienced shooter who wants to learn.
