Double Bell 24 Round Green Gas Magazine for Glock (VFC System) & Compatible Airsoft Gas Blowback Pistols (Model: Standard)

"works decently on my Elite force Glock 19 gen 3. its a bit finnicky though, as there is a slight bit of friction on entering the mag, which means you might have to smack the mag lightly so that the mag release engages. might require sanding. Cycles decently, but doesn't cycle all the way, slide stops about 1cm from its full length, although this doesnt prevent shots from cycling. will have to test on field, will update when that happens. interestingly, i got 2 mags, and one seems to be slightly thinner than the other, meaning both operate slightly differently (one engages the slide lock when empty, the other doesnt)

"No feeding issues on a 25 rps aap build. Baseplates need to removed to access fill valve. Easy fix with a drill. Extended baseplate version comes in red for some reason. Good value otherwise.

"Feeds perfectly on my VFC Glock 45 but the baseplate came in red.

"These do not cycle the slide all the way on the Sai Blu. I'm not sure if it's because the weight of the slide or a lemon of a mag. I'm being sent a replacement, if it works I'll delete and write a new review as an update.

"Does not cycle on my Elite Force Glock 19 despite the description saying it is "compatible".
