I also carried the P365 from the moment it released until the XL came out. I do agree the the 365 is the same grip length as the XL, as long as you are using the 12 rd mags. But, the reloads on the 365 always got stuck on my palm. Not so with the XL. And I love running dots on my pistols so the 507K is awesome and works very well under nods. IMO it’s one of the best carry options out there. Very accurate and reliable.
