Description

Take your defensive training to the next level with the SIG Sauer P320 X-Carry Blowback Air Pistol. With a realistic feel and 1:1 ergonomics, this pistol allows you to use your holster to train for things most ranges restrict, like drawing and shooting. This semi-auto pistol has an SAO (single action only) trigger and a drop-free 21-round magazine with ambidextrous controls. 

It’s made of metal and polymer with fixed, high-contrast sights to help you land accurate shots while training. The barrel has a smooth bore that shoots 4.5mm BBs up to 350 FPS. Adding realism to your home training is a reciprocating slide that mimics recoil while shooting. The slide locks to the rear to increase your effectiveness in training drills and it runs on a single 12-gram CO2 cartridge housed in the magazine. Its dimensions are 7.3 inches long and weighs 1.45 lbs to aid in realism.

If lobbing 9mm rounds downrange at your target is starting to get expensive, then check out the SIG Sauer P320 X-Carry Air Pistol. Buy yours today from Pyramyd Air.

Accuracy is what I expected from a smooth barrel BB gun/ I hav several SigSauer BB pistols and this is my favorite Very accurate replica suitable for training, plinking and fine in general. I have never had ANY problems with Sig Sauer CO2 BB and Pellet Guns. I prefer the pellet guns. Reliable and well made.

Make it TRULY RMSc MOS.ready

Put a dab of Super Lube on the tip of every CO2 cartridge. First time use, load one of the CO2 cartridges that has airgun oil in it, then use one of those cartridges every 5 CO2 changes. I've never had a leak and I always keep a CO2 cartridge loaded and ready. This should be handled and stored as if it was a locked and loaded firearm. It is NOT a toy and if improperly used, it could cause property damage, injury or death. Be careful when around law enforcement with this. Thgere have been instances where innocent people with this gun visible by law enforcement have been mistaken for a thread with deadly results to the CO2 gun owner. I mount a combo compact 1000 lumen flashlight and green laser on the lower rail.

Size, conformation to Firearm version, 2" groups at 14 yards (what I expected) with H&N Terminator 7.25gn pellets. Blowback, magazine reliability, pellet and CO2 loading. No jams and no other problems. I like the Optics cutout.

NOTHING!

Use the pellets that I suggested or wadcutters of same weight. Make sure pellets are properly SEATED in the belt. No part of a pellet should stick out of front or rear of belt. I put "Airgun Oil" (Never any cleaning or lube meant for a FIREARM), a little but on the pellets in the belt and pellets. Push the belt around 2 or 3 cycles so the belt through about 2 or 3 revolutions so oil is LIGHTLY coated on the belt and pellets, LIGHTLY. I also put a DAB of Super Lube Silicone GREASE ON THE TIP OF EVERY CO2 THAT I LOAD. For the very first CO2 through the gun, I use the CO2 (comes in packs of 5) that as silicone OIL in with the CO2 gas. These procedures will give you optimum reliability of gun and all seals/o-rings. This is not a toy and I personally recommend that the gun should be handled and stored AS IF it was a firearm locked and loaded. IMHO anyone under age of 18 should be CLOSELY supervised by an adult familiar with this gun and firearm safety in general.

Workmanship, decent accuracy at 10 yards or less. Realistic blow-back. Reliable. Perfect replica of the powder burner P320 XCarry. Never a jam. And VERY FAST shipping by Pyramyd Air.

Not 1 single thing

I have several Sig Sauer CO2 powered pistols, mainly M17 P320 variants BUT This 320 XCarry is the next generation of this realistic firearm. Improved magazine and magazine loading and CO2 insertion and piercing. The workmanship is IMHO, is outstanding. I am waiting for my SigAir red dot to arrive. I mounted a compact 1000 lumen with a green laser on the lower picatinny rail. I'm in the airgun business ( AirgunDirect.com ) and this isn't my "first rodeo". in 1 day this has become my favorite CO2 powered pistol. I really appreciate the 23 round magazine. I usually shoot every day for 2 or 3 hours a day, mostly with my RAW and FX .30 caliber competition guns, but I will work a few magazines of this gun into that daily routine. This Sig Sauer 320X Carry made me want to go out and order the firearm version P320 Xcarry from SIG, but then again, I could not shoot that every day or even ONE day in my backyard. I'm really done with powder burners. "Airguns Can".

Over all look and feel

The trigger could be better it’s quirky and on heavy side. Thus only 4 stars

It does not like copper head bb’s It goes jam city. Shoots fine with steel bb’s

This is such a great airsoft version of a great platform. It is so much like the regular caliber and makes a great practice tool. With the ability to install optics, lasers, and flash light, this is truly a great deal. Great job Sig Sauer. Thank You Pyramid

Nothing

BUY ONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Fit and finish are fantastic! The action operates like the real steel. Quite enjoyable to shot. Love the feel and balance of this Sig Co2 air pistol.

So far so good! At this point no complaints.

This is definitely a fun pistol to shot at home or in the field. But I would recommend purchasing a spare magazine, I ordered an extra one with my purchase of this model of this Sig Co2 air pistol from Pyramyd Air. Then let the fun begin!

The realism.

I would have to say that I am very disappointed in this pistol overall. Especially wit the brand Sig Sauer behind it. The trigger pull is not consistent. Its ranges anywhere between 7lbs to over 20 lbs. I bought an extra magazine and the slide doesn't lock to the rear after the last round is fired. Also after each round is fired, I have to rack the slide to cock the pistol in order to fire it. I think it might be something wrong with magazine because it doesn't do it with it the other one. In closing, I am very dis satisfied, would not recommend to anyone.

Buy something else.

Call Pyramyd Air support with your issues. I love mine and it does lock back after the last shot. Pyramyd Air will make it right.

Looks like the real gun

Make one that works, this one does not.

I sent it back immediately but I still haven't received my credit card refund.

Sandy Aug 24, 2026

I suggest that you email support@PyramydAir.com re your refund and any other issues that you have. Mine works fine. I love it. Yes, trigger pull is heavy. I can't figure out why.

I'm disappointed with my purchase, it's supposed to be semiautomatic but it's not firing correctly. Now I have to send it back and wait even longer to enjoy the product as it was intended for.

Buying the product to begin with

Read the reviews others have had the same thing happen to them and it's not cool for a company to operate with these standards

Sandy Aug 24, 2026

mine works perfectly. Now my favorite CO2 pistol. Pyramyd Air support is great, did you contact them when you had a problem? ( support@PyramydAir.com )

Great plinker

Slide and trigger make it lighter on the pull

Buy extra mags once you handle one you won't put it down love firing this gun.
