Description
Umarex Glock G19X MOS 18-Round Green Gas Magazine by SRC (Coyote Tan)
This is a spare 18-round green gas magazine for the Umarex Glock 19X MOS gas blowback pistol made by SRC, finished in coyote tan to match the pistol. Spare magazines are essential for any GBB pistol: they let you carry more ammunition and keep gas on hand as each magazine cools.
Umarex holds the official Glock licence for airsoft replicas, and the 19X MOS by SRC is an optics-ready version of the popular 19X.
Using spare magazines
Gas magazines cool as they are used, which lowers pressure and can make the slide cycle more slowly, especially in cold weather. Rotating between two or three magazines lets each one warm back up between uses, so you get more consistent performance through the day.
Fill the magazine with gas held upside down and in short bursts, and stop when gas spits back. Load BBs by pulling the follower down and feeding them in from the top or with a pistol speed loader.
Fit
A retailer listing for the Umarex Glock 19X MOS by SRC gives the Umarex Glock 17 Gen 5 MOS gas/CO2 magazine (SRC) and the Umarex Glock 19X gas/CO2 magazine (SRC) as compatible, and lists the pistol’s green gas magazine as 18 rounds.

Compatibility
Made for the Umarex Glock 19X MOS by SRC. Magazines for other makers’ Glock replicas, including other Umarex versions made by different factories, are not always interchangeable, so check your pistol’s maker before ordering. Use green gas as named, never lighter fluid or butane.
Care and maintenance
Store the magazine with a small amount of gas in it to keep the seals supple. Lubricate the seals and fill valve with a drop of silicone oil now and then; avoid petroleum-based oils. Do not overfill, and wipe the feed lips clean after a muddy game.
Who is it for?
This magazine is for owners of the Umarex Glock 19X MOS by SRC who want extra capacity and the benefit of rotating magazines during the day.
Please note: Gas and BBs are not included. Always wear suitable eye protection.
