I own and have carried a 43x with EPS Carry. Love that gun, though my personal preference for CCW is a Glock 17. I have close to 2k with the 43x and no failures. The grip is laser stippled and have trigger guard undercut and texture. I also have an Overwatch trigger. So not close to the cost of the base gun.
I have shot prob over 2k on P365 and P365XL, both with irons and RDS. I've heard some issues with early models, including one 2a member's gun. From what I've read or watched on YT, seems like the issues with the 365 platform has been addressed. To the point where maybe the P365 gets "improved" as things go and replaces the P320 series.
Overall, recommend you (or anyone) try for yourself. The ergos/feel between the 43x and P365 is pretty distinct. Overall, I would say nothing wrong wtih the P365, but just decided early on to go with the 43x and just stuck with it. Especially after I invested in holsters, mags, etc.
