GSG magazine Tuesday, October 6, 2026 Reviewer: Victor Vazquez from Kuna, ID United States   It didn’t work for the GSG magazine. However I also must say. It does work flawlessly with the mosquito magazine Was this review helpful to you?

A Necessary Upgrade Monday, August 24, 2026 Reviewer: Rob Fagan from Grand Rapids, MI United States   Taking a clip from 10 to 16 rounds is a must, less time getting rounds down range. I have 3 clips so that's 18 more rounds before reloading compared to the factory 30 rounds. I only load mine to 15 to match the round count in my 40 but being able to have 17 rounds, 1 in chamber & 16 in clip is amazing. Was this review helpful to you?

GSG Firefly Mag Upgrade Friday, May 22, 2026 Reviewer: Maxwell Hille from Saint John, WA United States   Took a little tuning on the follower to move freely up and down the mag body, but took a pistol I was never fond of and made it pretty slick! Improved feeding quite noticeably, definitely recommend this! Don hesitate to pick this up! Was this review helpful to you?

16 round GSG Firefly magazine upgrade Monday, January 12, 2026 Reviewer: Don Fitzgerald   Had to use Emry Board and file all sides a little. Follower would get stuck last 1/4 to the top, you could push it up or down but wouldn't slide all the way. Little sanding with Emry Board fixed this. Works fine now. Was this review helpful to you?
