Add an extra 4 round capacity to your GSG Firefly magazines with this custom magazine follower from Taylor Tactical supply.
- Converts 10 round factory magazines into 14 round magazines
- Compatible with extra capacity base pads
- Suitable for LBP pistols
The follower replaces the standard follower and thumb assist, allowing room for an extra 4 round of .22LR. This means the thumb assist operated last round lockback will not operate, instead the follower is designed to rise and block the slide going forward. Please note that this will release the slide when removing the magazine.
For best results TTS recommend reversing the direction of the magazine spring so the top of the spring points to the rear.
Fits magazines for the GSG Firefly and Sig Sauer Mosquito.
GSG 2025 magazine update
GSG refreshed their Firefly magazine body (part number 400.10.02) in 2025. If you have the newer magazine the front of the follower will need a light sand with some oxide paper for clearance. Older magazines do not need this.
Put some fine grit oxide paper on a flat surface and wipe the front edge of the follower across it a few times to gently relieve the rounded front profile until it is moving smoothly in the magazine with the spring fitted. Very easy, you could also use a small file.
