Converting my P320C back from 357Sig to 9mm

My other 2 9mm pistols (KelTec P11 & Ruger LC9) are loaded with 115gr Hornady Critical Defense.
The sharper taper on the bullet feeds much more reliably in the P11 than wider-mouthed rounds like Federal Hydrashoks, which would occasionally hang on the feed ramp.

I don't recall what I used to keep in the 320 when it was originally a 9mm.

Got good responses on my similar rifle thread for .223/5.56 options, hoping for more of the same here.

Thanks, gents!

I load Federal HST 124 grain in my 9mm pistols. But reliability is the key. Any major manufacturer's SD rounds should be fine as long as they reliably function in your pistol.

If you like Hornady, the Critical Duty rounds might be a better choice because those are designed for service-sized pistols like the 320.

Remington 115 gr JHP or Federal 9BP

I know quite exotic.

My thought was using the same rounds for practice and sd

I carry the Hornady Critical Duty 135gr Flexlock or Speer Gold Dot 147 or 124 gr JHPs.

124gr HST standard pressure.

124 +P HST

My primary HD gun is loaded with Speer GD 124 +p. My primary carry gun is loaded with HST 124 standard velocity.

I am heavily invested in Ranger 147. I keep a couple of cases of Federal BPLE tucked away. They are old tech but have a good track record and will feed in just about everything.

HST or Gold Dot 124 grain. Some +P some not.

I honestly don't get too hung up on this stuff and I am happy with any reasonable defensive round in common use (I'm not going to use RIP or DMFR5000 or IKEEELU+P or some such) but honestly beyond that I figure as long as can get shots on target I am good and I worry less about the specific bullet. (I am not using FMJ of course)

HST 124 grain +P

Federal HST 124 +P or Speer Gold Dot 124 +P

Standard pressure Gold Dot 124

Speer 124 grain +P Gold Dot.

I did some backyard ballistic testing on tshirts and water jugs. It’s almost completely unscientific, and was with .40, but I had failures to expand on the Hornady and HST. Gold Dots took the day. I only carry Gold Dots. In 9mm, they’re 124gr, in .40 they’re 165gr.

Home defense- Speer Gold Dot 124 grain +P and I don't think I'll ever move away from this choice. I've been using it for a very long time, almost two decades.

About town- Federal HST 124 grain, either standard velocity or +P, depending upon what shoots best in a particular pistol

On the road- Hornady Critical Duty 135 grain +P, for its penetration characteristics

147gr HST pretty much across the board with a few exceptions.

The 320 really favors a 124gr bullet.
When I did carry the 320, it was either 124 gr HST or Gold Dots.

Seems to be a lot of echoes.
I'll have to see if any of my local sources have some of these options & try them in the 9mm 320 when the parts get here.

Thanks all

Federal HST 124 grain 9mm in my carry gun and 2 spare magazines with about 6 boxes on the shelf.

I lucked out at Christmas gun show in 2019 right before COVID lockdowns and riots by getting Federal 9bple for $330 a case out the door during the last hour of the show so I got 3 cases put away,guy didn’t want to take them back home. Older design but like others have mentioned it works in every gun and still does the job

Federal HST 124gr +P and Speer Gold Dot 124gr +P, but mostly HST right now because I have a bunch of it.

Hornady Critical Duty 9mm 135+p.
