Who exactly is this random F? Is he living in the desert or something? MAC was one of the first and loudest complaining about P365 issues when they first came out and now he not only carries a P365 XL most of the time, he has a standard P365 and reviewed the Macro and had nothing bad to say about any of them. I trust his opinion (and other YT personalities) much more than this guy. I haven't carried my Macro yet, but I've put a couple hundred rounds through it without any of the problems this guy describes. Will keep an eye on things, but I have a hard time believing the Sig Nitron finish has the issues he's complaining about.
Could have a holster that doesn't cover much, like one of those minimalist holsters. Or maybe doesn't wipe off the sweat and/or lube correctly for carry in hot months? I know I've found with two carry guns that sweat gets in places you don't want and causes issues. I now wipe down good and also make sure the mag release and other areas are well lubed, as they tend to get rusty during carry.
FWIW, I bought the Macro and liked it so much I bought a Macro Lower to run on a 365x slide/upper and chopped the lower down to accommodate. I’m not putting thousands of rounds down mine, but I have shot them both a fair bit. They have been 100% reliable, shoot great, and fit my hand like a glove. Even got into the red dot scene, which was challenging at first, but really enjoy it now.
I would think if there were widespread issues like the guy in the video had, you would see it everywhere. When the P365 came out and had striker drag issues and firing pin issues, there were tons of videos and forum posts on the issues. I'm not seeing anything other than this one guy talking about this and I watch and read a ton of reviews on the gun.
