I have the P365 original model. I probably have around 1500 rounds through it without a feeding hiccup so far. I haven't read of any feeding issues with my model, although there were other quality control issues I had to iron out.
I thought I might have feeding issues with the 12 round mags but didn't. Reason being the pinky extension. I had a baby Glock 10mm years ago that had feeding problems whenever I used the extended mags with the pinky extension. When I gripped the pistol, my finger would pull the bottom of the mag rearward aiming the bullet directly at the feed ramp. The problem would get worse with hollow points and a carboned up feed ramp. I haven't shot or handled an XL, but maybe this could be part of the problem, although I think the SIG mags fit much tighter than the Glock mags did the way the recess is cut in the SIG grips.
