Glock 43 barrel

So for Christmas my dad passed me his Glock 43. Its a cool gun for sure but I notice there's obviously some newer options available out there. I know when the 43x came out they updated the barrel to a more precision barrel. I also know the the 48 is pretty similar in size but over half an inch longer. My question is how much of a difference do these make? Should I look for an aftermarket barrel for my 43 to make it shoot more like a 43x? Do I save up to buy a 48 or 43x? Are they that much better than the 43?

To be clear I have started to carry this and its comfortable and I like a lot about it. Been shooting 2 times with it and could improve in accuracy for sure but that is also probably practice. I just want to have the gun as good as it can be you know?
