The EMG SAI series of WE-Tech G-series magazines replicates the realistic round capacity for their corresponding model. This was done in an effort to further promote practical firearms training with Airsoft GBB pistols. The base of the magazine is made from an extremely durable nylon-reinforced polymer, and has been redesigned for easier grip on the magazine.

The SAI-17 type magazine will fit virtually all of ZEV, ATI, WE G-Series, M-Series, SAI-17, SAI-19, SAI-34 (and compatible) series Airsoft GBB pistols. For shorter grip models such as the 19, the magazine will extend out of the grip.
This magazine came with a insert which limits the capacity of the magazine to 15 rounds, optimized for law enforcement training. This limiter can easily be removed for this magazine to be converted to 23+1 round standard magazine.

    "Good mags so far, only a couple of drawbacks; one is the allen key needed to tighten CO2 cap is NOT included (which is why I knocked off a star) and its a smaller size than used by KWC...

    I'm getting up to 85 shots per mag, which is real nice- in my stock WE G18c.

    The other drawback is I had to trim some flash off the inside of the feed lips (yes, they had to be removed to do this). Its easy but shouldn't be required on a new item.

    I trimmed the follower shuttle (plastic bar that rides inside follower spring) down to increase capacity to 17bb (to match capacity shown on back of mag) and it can be removed completely to allow a max of 25bb.

    "This mag works great, base plate is a little funky IMO though. Other reviews have stated quickly/instantly stripping the threads where you tighten the CO2 into the magazine. I went into this knowing that was a potential problem, and let me tell you the second I tried to install a CO2 I saw why! When you first start to tighten the cap for the CO2 into the mag only ONE thread is engaging, meaning the entire load is on a tiny .5mm strip of pot metal! No wonder this strips! I'm still working on a permanent solution but what I have been doing in the interim is using a longer allen key to reach through the cap and apply downward force directly onto the C02 as I tighten the cap, this prevents the caps threads itself from being what drive the CO2 down to puncture and takes the stress away from the weak threads. This is a bit of a pain and makes CO2 changes less than drama free but it works. Once the C02 is in the magazine feeds great and has a great kick with the added pressure of CO2. On my Xcortech X3200 Mk3 I showed a 30FPS increase with .2g bb's between green gas and CO2 on my WE G19. Also, they state this is a 15 round magazine, the only thing limiting this mag to 15 rounds is a small plastic bar installed under the magazine follower, this can be VERY easily removed to return this mag to the 25 round capacity of its green gas counterpart.

    All in all everything is great about this mag, if WE had increased the initial thread engagement of the cap this would be a perfect CO2 mag, unfortunately with that one flaw WE definitely missed the mark. I would still recommend these mags just keep that problem in mind.
