Colder temperatures tend to result in slower velocities while warmer days drive pellets faster. A few of these include the temperature, altitude and projectile design. Many factors alter the muzzle velocity of the projectile. The metal parts appeared well made and the plastic that made up the frame was well molded with no sprue and only faint molding lines. My test gun was finished in coyote tan, The finish looked very good. The slide does reciprocate mimicking that of a real firearm. Sights on this review gun are a 3-dot style similar to what you can find on a normal SIG P320 pistol. This, unfortunately, introduces some wiggle into the feel of the grip. The back strap comes off with the magazine well to access the CO 2 cartridge compartment. This is probably because it is designed to come apart. For example, the air gun has a less solid feel to the grip. It did not feel identical, but it was close. My sample P320 air pistol had a similar feel to that of the firearm version. With only about one ounce of difference between the two guns unloaded, I’d say the weights are close enough to live up to the company’s claims of similar weights. Without a CO 2 cartridge or pellets in the magazine, the gun weighed 28.2 ounces. However, I weighed my sample P320 air pistol on a postal scale. That’s a fair difference between the two.
According to the company’s website, the full size Nitron P320 weighs 29.5 ounces unloaded. SIG lists the weight of the air pistol at 2.2 pounds. I highly recommend buying a second to go with this pistol.
An extra magazine or two should be considered mandatory, but SIG only includes one with each gun. It works, though I found the loading process tedious. Each pellet must be fit individually into each hole in the chain. It is a flat magazine that hinges open to load BBs or pellets into a chain-type feeding system. You can also buy them easily online at places like Amazon.Ī 30-pellet magazine feeds this gun. These projectiles remain the most common for air guns, and should be easily found at any sporting goods, Walmart or similar store. Under ideal conditions, SIG states the cartridge can propel a projectile up to 430 fps.
These are the small, metal canisters that have traditionally powered air guns, paintball guns and a variety of other things. The SIG P320 Air Pistol is powered by 12 gram CO 2 cylinders. Different color/finish options are available for each model of air pistol. The names make it fairly obvious which air gun is modeled after which firearm. SIG SAUER describes the P320 Airgun as being part of a “next-generation air pistols” line that “closely measure up” to the centerfire handguns sold by the company.Ĭurrently the company offers three basic models: the P320 Air Pistol (the subject of this review,) the 1911 MAX CO 2 BB-Gun and the P226 Air Pistol.
