Ammo choice for the P365

147 grain HST and 115 grain Gold Dots have both worked well.

I have not found a load mine doesn't like with somewhere between 3 & 4K rounds. All hand loads, a little of everything but mostly 147 and 124 JHP.

No issues with any rounds on my P365 & P365XL

147 gr. Golden Sabers or HST. Pretty nice pistol, but I wish the grip was just a little thicker.

Mine shoots any FMJ I feed it. And i choose to use the SIG 365 V-crown hollowpoints. Just my choice-they’re pretty cheap at academy.

I use the 150 grain Federal Micro HST load in my LC9, I’m sure it’ll work well in your new 365.

Congrats on buying a great carry gun!

Stay safe.

I have found my 365 feeds anything i have put through it. including home cast pc bullets.

I carry HST

So far mine has not had an issue with anything I've fed it.

The P365 is my 24/7 pocket carry and mine has been 100% reliable with everything from 115 grain JHP factory to 124 and 147 grain cast handloads.

Good article on 9mm carry ammo.

Heavy bullets can have expansion problems out of a shorter barrel, so 147 gr. might not be great.

The Federal Tactical Bonded +P 135 gr seems to expand and hold together adequately in anything from the P365 (3.1") to the MP5 (8.9"). It seems to be on the lighter end of recoil for +P. I have a good source locally for them and they work in everything so it tends to be my round of choice.

I find a lot of decent choices in 9mm. Even the WWB 115 gr JHP seems to work pretty well in shorter barrels.

I would much prefer WWB well tested for function to something to expensive for someone to test adequately.
