I saw that the Glock 43x fits really well with me, but I don't know what I want yet.Welcome from Gulf Breeze. Like Raven said, borrowing or renting some pistols to try out before you buy is a great idea. The manner in which you dress and how you plan to carry will also affect your firearm choice.
With the new Shield brand mags those G43X's have the same 15+1 rounds of 9mm as a G19 but in a way smaller package. A respectable choice. I carried a 43X and went back to carrying a G26 and then a G19. Mainly for mag compatibility with my carbines and $15 used mags at the gun shows. The 43X doesn't have mag compatibility with anything except another 43 or 43X, and Shield brand 15 round mags are like $80 a piece on average on the forum and eternally backordered on the Shield website.I saw that the Glock 43x fits really well with me, but I don't know what I want yet.
