The Green Gas Magazine for P320 M17 (21 bb) produced by VFC / SIG AIR ProForce is the original replacement to maximize the firepower of your sidearm. With a realistic weight of 278 grams and a Full Metal structure, it guarantees excellent performance and seal. Being the entire P320 line "Dual Power", this gas magazine is the perfect purchase both as a replacement for the M17, and as an upgrade for the compact M18 (on which it acts as a very comfortable grip extension). Available with polymer baseplate in Black or Coyote Tan!

Full Metal Construction and ProForce Realism:
Designed under official SIG SAUER license, this magazine meets very high quality standards. The body, made entirely of heavy metal, brings the weight of the magazine to 278 grams. This detail is essential for the most demanding players, as it faithfully reproduces the balance of the real firearm and allows the magazine to drop freely when the release is pressed for lightning-fast tactical reloading. The latest generation VFC valves ensure a powerful and constant firing cycle (blowback).
Total Compatibility (The trick for the M18):
This "long" magazine is standard for the P320 M17 (the Full Size version of the US Army), where it fits perfectly flush. But the real magic happens if you own the short version P320 M18! By inserting this magazine into the M18, the enlarged polymer baseplate will perfectly match the profile of the grip, acting as a "Grip Extension". In this way, those who have the compact pistol obtain a longer, more comfortable and stable grip, identical to that of a Full Size!
Do you have the CO2 version? Get this!: All VFC P320s on the market have a "Dual Power" internal mechanism, designed to withstand both CO2 and Green Gas. If you bought the pistol in the CO2 version (excellent for the winter), we strongly recommend purchasing this Green Gas magazine to use it in the summer! With summer temperatures, CO2 rises to pressures that are too high, risking making the weapon work badly and exceeding the power limits of the field. With Green Gas, you will always play safely!
M18 Owners, this is for you: If you have the M18 (the compact), this magazine will revolutionize the ergonomics. The standard magazines of the M18 often leave the little finger a little "hanging". By inserting this long magazine of the M17, the baseplate will perfectly close the line of the frame, giving you a full-hand grip that will drastically improve the accuracy in rapid shots.
O-Ring Issue (The sacred rule): VFC makes exceptional magazines, but they require the right care. When you put away your equipment at the end of Sunday, NEVER release the remaining gas by pressing the valve with your finger! The thermal shock would freeze the seals, cracking them. Leave the magazine with a little gas pressure inside: the silicone oil will keep the seals swollen and perfect.
