SIG Sauer P320 Pistol

  • Uses a 12-gram CO2 cartridge
  • Semi-auto
  • 30rd belt-fed mag
  • Manual safety
  • Fixed white dot sights
  • Blowback
  • Metal slide
  • Polymer frame
  • Weaver/Picatinny accessory rail
  • Same styling and trigger pull as P320 firearm

Please Note: Your P320 will feature a 30rd magazine, however, if you purchase additional spare magazines, Sig Sauer has reduced the capacity to 20rds.

This 30 shot repeater debuted at SHOT Show 2017, and Sig Sauer has once again set a new standard for CO2 air pistols.

Built with a sturdy metal slide against a polymer frame, this Sig's claim to fame is its 30 round capacity. The first pistol of its kind, this belt-fed semi-auto is capable of firing both .177 pellets and BBs as fast as you can pull the trigger! Featuring realistic blowback, and fueled by a 12-gram CO2 cartridge held in the grip, you can propel your ammo choice at up to 430fps (depending on ammo weight/composition). With this many shots, this pistol is great for hours of plinking fun!

Recently selected by the US Army to replace the Beretta M9, this pistol is destined to see action overseas for years to come as the standard Army issue sidearm. This replica Sig has the exact same trigger pull as the real gun for a real feel, ideal for owners or fans of the real pistol, but less costly to shoot. Shooters can mount a flashlight or laser sight to the Weaver accessory rail and keep their target in sight.

If you like replicas with more shots with less reloads, this is the air pistol you've been waiting for!

Available in black or coyote tan.

Things I liked: Accuracy, same weight and balance as my full sized Sig P250 9mm

Things I would have changed: Eliminate the blowback feature--a useless waste of gas.

What others should know: I don't know why Sig designates this air gun as a replica of a Sig P320--it is not. The gun it replicates is the P250, a DOA semi auto that is no longer in production. If you own a P320 and want to use this airgun as a training aid you will be training only for the first shot, which is useless since the tough part of a DA/SA auto loader is the second shot. I've never owned an air gun with the blow back feature before. Since it doesn't cock the trigger, what is the point? Just a waste of gas. Also I experienced multiple jams with the 30 rd mag until I saw on You Tube that you have to carefully press the pellet all the way into the mag. Somewhat of a pain in the neck. Also, why is it a 30 rd mag? My 9mm Sig has a 17 rd mag. For a replica air gun done right, get the Glock 19 GEN 3.

Things I liked: Nice feel, reasonably accurate.

Things I would have changed: This gun has no slide lock after last round, that would be very helpful when dealing with 20 rounds.

What others should know: The airgun industry uses the terms "semi-auto" and "blowback" loosely. With this gun every trigger pull advances the next round, pulls back and releases the (internal) hammer. This begs the question: what does the blowback do? Nothing, only to simulate a firearm, mostly a waste of CO2. The trigger pull is always double action and feels that way.

  • Pixly from USA asked:

    I've seen many reviews mentionning the fact that it jams often,is it really that bad ?and does it work with pointy pellets as those predator polymags?

    • jose from USA:

      Yea its that bad and doesnt works with pointed pellets

    • Shane from Canada:

      When I first got it I had no issues using crosman 7.4 wadcutters. Then I switched to 7.9 hollow point and it jammed all the time, pellet would stay stuck in the clip. I tried crosman 7.4 premier pointed and have had 1 maybe 2 jams in the last 400 shots. IMO it needs lighter pellets with a small head.

  • Nicholas from USA asked:

    on the sig P320 co2 pistol can you use crosman .177 cal destroyer pointed expanding pellets

    • Terry from USA:

      From everything I have read about all of these Sig Sauer pellet guns (and I have been researching a ton), they don't do well with pointed pellets. So if that's what you want to use, I'd steer away.

  • Hugh from USA asked:

    Anybody have experience shooting sharp pellets like H&N Hornets ? Thanks.
