"Full disclosure I have only bought the green gas mags.
I really love this gun, but the mags have an issue where if the spring is pulled all the way down to load bbs and then released, the force of the spring on the plastic tip will snap it right off and send it flying about 30 ft. If the tip on the spring were just a little easier to keep hold of, it wouldn't really be a problem...

One thing I do really love about these Sig mags are - due to lack of experience with airsoft handguns, imp not sure if this is generally applicable to most handguns - interchangeable, and both the GG and CO2 mags will fit into the M17's mag well and function properly.

"I bought 2 of these. Broke one of the mags by pulling the spring down and letting go. Low quality on the tip.
by Deven K. on 08/13/2020
"As with previous reviews the main issue with the CO2 mags is that they are made relatively cheap. The Base cover is made of a cheap and brittle plastic that has an extremely small lip to clip it into the mag, which breaks from even small falls onto hard surfaces. I had one pop off just from a 12 inch drop onto my desk doing dry reloads when i first got the replica. The other problem is the spring, which can break the feeding lips under the force of the spring. its good to practice only holding it part way down while reloading and slide it down more as needed. another fix can be to shorten the spring by ~.5" to .75" and more as necessary.
