I should have added that my friend brought a Kahr CW9, a Sig P938, a couple of compact Glocks, and two other guns I didn't care for. One had the longest trigger pull of any gun I've ever fired.
My friend carries the Sig P938. I didn't feel like I shot better with the P365 than I did with the Kahr or the P938. All were nice but unfamiliar to me. For me the advantage of the P365 XL is the larger handle and the availability of a 15 round mag. Not that I'll probably ever need the extra rounds, but it's cool and doesn't hurt to have just in case you do need it.
