I recently traded a 9mm P320c for a .40 P320c. I was having ejection and brass to face problems with the 9mm. After sending it to Sig, it still wasn't fixed. I had been wanting a P320c in 40 so I decided to trade it. The trade only cost me $50 at my LGS. I've put about 100 rounds of 180 Blazer Brass, 50 rounds of 180 HST, and 50 rounds of 165 Lawman through it. Not a single problem. I will say that with 180 grain ammo, there is little difference in recoil compared to 9mm +p ammo. But when I shot the 165 Lawman, there was a definite increase in recoil. So if anyone wants a change from 9mm, the .40 P320c seems pretty good. There is fantastic defensive ammo available at cheap prices. And the recoil from 180gr is negligible. I'm looking forward to shooting steel and bowling pins.

Do you have experience with .40 in another pistol?

I started with a .40 SP2022, picked up a P320 to shoot 9mm and though I've more trigger time and rounds through the .40 and it doesn't seem as bad as most make it out to be, but it still is slightly worse than the 9mm.

I agree. I don't even notice the difference between my 250 9mm and my 250 40SW.

Yes I have a Glock 23 Gen4. The P320 handles 40 better than the Glock.

I have P320 C's in both 9mm and .40 S&W. I find I shoot a bit more accurately with the 9mm but prefer the .40 for plinking. I also notice little difference in recoil. Ammo prices are still better for the 9mm though.

If you want to ramp up your P320 C .40 a bit, Get a .357 Sig barrel. It drops right in the .40 slide and uses the same spring & mags. .357 Sig ammo is coming down in price over what it was just a year ago.

dukemason Most shooter have good luck with the 9mm p320 if they stay with a mid weight bullet and a reliably good brand . Some from time to time have some quality control issues and if PL id down brass to the head and cycling issues do happen .


Your trade for a 40 is a great choice if you get into reloading !! Getting a 40 down to 132PL is practical at least after a few hundred round . The recoil assemble in the 9mm is the same used in the 357sig and 40sw . Even the lite slower 135gr 40ammo can make around 1150fps from a 3.9" barrel and cycle reliably and barely exceeding many 124gr and 147gr 9mm ammo .

Basic reloading kits are affordable too an help to keep cost affordable and at a power level you want for fun or practice ammo too .

I tend to stay with a 155gr bullet weight in my 40sw p320 and ammo can be as slow as 1000fps or 1300fps . It will do anything a 357sig can . a 135gr can exceed 1400fps with factory ammo or reloads

Yes on the 357 Sig barrel. I ordered one yesterday, but it's back ordered so it will be a few weeks. Since I have a 357 barrel for my Glock 23, I already have a decent supply of 357 Sig Gold Dot and Golden Saber Bonded.

Actually my plan was to buy a 357 P320c and add a 40 barrel in the future. But I couldn't find a 357, so I started with the 40 instead.

I'm not reloading yet but I've been saving my brass. Makes sense to load 155gr a little lighter for target shooting.

Sig has a couple of .357 C barrels in stock for $189:

You can usually do better elsewhere but that can result in a backorder.

I saw that one but Sig is saying this is the correct barrel for the P320c: BBL-MOD-C-357

I'm not sure what the difference is. But I ordered it from Sig.
