For those with smaller hands, the G43X might be a good option. However, like most things, there are going to be trade-offs.
The G43X will have a much longer grip height than the G26. The only way to squeeze 10 rounds into a double stack while slightly increasing the grip width is to lengthen the grip. I find longer grip heights are more of a problem to conceal than a slightly wider gun. I can pocket carry a G27 (same size as G26) easily during 3/4 of a year, excluding warm weather. I can't easily pocket carry a G23 or G19.
A G26 can also use standard mags used in the G17 and G19. The G43X will not have this ability.
IMO, the G43X will be competing against the G26 in the Glock line-up, so G43X sales might increase at the expense of a decline in sales of the G26, so it still appears to be a wash for Glock if someone is determined to buy a Glock.
