What do you want to know
I have the X, the XL, and even the newest P365 with the "P" in the sku. All new P365 come optic ready. That's new as a month ago or so.
The P365 does "it" better than most. You can easily change the grip to larger. I like the curved trigger more than the Sig straight trigger.
The P365XL converts up or down....but I have found the P365 with the shorter barrel, for me, shoots no worse than the larger. Here are two of my converted P365 grips carry guns, just color changes:
Couldn't be more simple to swap the grip.
On mags, if you look at that last pic, I have all mag configurations for the 10rnd small grip. All work 100% That's 10, 10 +0 base pad, 12rnd, 15rnd, and 17rnd in the 10rnd grip. It works great. Only the 15rnd Sig mag is kinda weird because they didn't close the back (top picture).
The Gen5 trigger can be swapped to the now $60 Glock oem performance trigger. That said, the P365 is pretty darn good. Better than most. Approaching Walther level, almost
I think the P365 series is a winner.
