Asking for recommendations on ammo

I will be picking up my p320 in a couple of weeks and was wondering if anyone has recommendations on ammo for it. So far I have 250 rounds of 9mm 115 gr FMJ (100 Tulammo, 50 rounds Aguila, and 100 rounds of Federal) All thoughts are welcome

Federal HST or Speer GD
Weights are your preference, +P is your preference.
But those are the 2 most popular and the 2 I use/recommend.

If you are going to be breaking in a new gun, I have always had luck with sticking with 124 grain for the break in all my new sigs. I heard it once and it has worked out well for me.

If you are talking about ammunition to break it in, suggest you stay away from steel, or aluminum case until after it has broken in, or you may start getting upset by stoppages, and malfunctions.

New Sigs are tight, and springs are strong, and in some cases, the generic 115 grain "Value Packs" may be a little "underpowered".

Make sure you clean off the "Preservatives", and use grease on areas where things "slide", and oil, where things pivot or turn.

I don't know what you have available ammunition wise, but you can get some bulk ammunition from places like Ammunition Depot, for 1000 round case of Federal or Speer 9mm 147 grain FMJ for less than $220 + shipping.

What the senses impaired squirrel says ^^^^

Clean and lube the gun first!! Don't skip this step. Grease slidey bits and oil the turny stuff.

Use the cheap ball stuff for "I wonder if this works" and range, and your choice of SD ammo (after reviewing "LuckyGunner ballistic tests").

I tend towards the heavier bullet weight side of whatever performs best. And if +P doesn't offer a worthwhile ballistic performance benefit, then why incur the extra recoil and gun wear?

Run enough of the pricey stuff to make sure it's 100% in your gun.

I am wondering about cast lead bullets for practice, as I cast bullets for my other pistols. I understand that the factory barrels are rifled, and not polygonal. Has the experience with lead bullets been positive?

A lot of using lead projectiles is their alloy, and speed, which driven. In most cases match grade cast bullets at reduced velocity are accurate, and economical. Problem in autoloaders, is velocity to efficiently operate the action, if you use a heavier slow moving bullet, you will probably be okay, and not get a lot of leading. Once again bullet hardness, and velocity plays a factor, but normally lower velocities would be an advantage.

If you cast and size your own, then you will have more flexibility. If you purchase your bullets, then it will be limited to what is available.

Years ago both revolvers and automatics used in competition fired predominately cast bullets, where polygonal barrels were rare in pistols IIRC H&Ks were about it, and they weren't that common. Revolvers in PPC, and M1911s in NRA Pistol were the rule!

Concur with the break in advice. I like to run 124 grain for at least 200 rounds, but 115 FMJ will do just fine. As for a defense round, any of the modern offerings from reputable manufacturers will do, but as stated, the most popular brands are Federal HST or Speer Gold Dot. Some other alternatives are Federal Hydra-Shok, Winchester SXT, and Hornady Critical Duty or Critical Defense.

My personal preference is a 124 grain standard pressure round in 9mm. I have run the Critical Duty, which is good stuff, but I like the consistency of the HST, which makes it one of the most popular rounds on the market. It performs well in a variety of guns from pocket guns to the long slide guns, and it has very good ballistic performance.

Another one of my preferences is the Speer Gold Dot. It is probably used by LE more than any other bullet, and it has an excellent street reputation. It is usually available, unlike the HST, which makes it a good go to round. There are some other bullets that are relatively new, like some of the frangible rounds, but I'm not sold on those as yet. Some of these are really light, but they're extremely fast, and the argument for using them is that the energy causes big, big problems inside the human body. I don't know about all that, so I stick with what has been a consistent performer for so many over the years.

I have shot Fiocchi 115gr FMJs through my P320 sc and they have been flawless. I also shot enough Fiocchi 124gr JHPs to be satisfied they are flawless as well. I've bought them at Able Ammo and they have been very reasonable.
