I LOVE my Glock 43X 9mm! It's compact, thin, 10+1 rounds, functions great and it accurate. I've got a kydex IWB CCW holster and a Blackhawk OWB holster that both work great!
If you want more rounds buy the Shield Arms metal mag release and the 15 round mags by them as well. I used these in my Glock 48 to great results.
Though I am not a Glock fan, I have several and was issued one for decades so am used to them. They don't fit my hand well, but they do tend to work well. If I am not carrying a S&W N-Frame or a 1911, I will throw a Glock 43X with the Shield Arms 15 round mags in a pocket holster or a belt holster and call it good. Though I do like my S&W 13-4 in .357 magnum just as much!
