Alternative Views:
The GSG FireFly High Capacity Magazine Upgrade converts your factory 10 round magazine to a 16 round magazine! With a round in the chamber and 16 in the mag, that's 17 rounds in gun! The High Capacity Magazine Upgrade replaces the factory plastic basepad and factory follower with an aluminum basepad and High Capacity Follower. The basepad is also longer than the factory plastic basepad and allows for more positive seating of the magazine in the gun. Additionally the aluminum construction is more durable than factory plastic basepads making your magazine less prone to breakage upon dropping.
PLEASE READ BEFORE PLACING YOUR ORDER
Choose whether or not you want your pistol to lock open on the last shot fired. The original magazine kits were sold with the Shockbottle follower THAT DOES NOT lock the slide open on last shot fired. The NicTaylor follower DOES lock the slide open on last shot fired but not like the factory magazine.

Since the button on the factory magazine is removed when installing these high capacity parts, the function of locking the slide open on the last shot fired is lost. That button on the side of the factory magazine is used to actuate the slide lock feature on the gun. The NicTaylor follower is designed to catch the slide itself and thus lock the slide back/open. This technique is used frequently on AR15 22lr conversion kits. However, when doing this the user looses the ability to drop the mag free since the magazine is essentially being stopped from falling free when the mag release is pressed. The user will either have to pull the magazine out or pull the slide back to its most rearward position and manually engage the slide lock. This will allow for the magazine to drop free. For best results when using the NicTaylor follower, we recommend reversing the direction of the magazine spring (see picture). This will help with more positive engagement of the follower and thus locking the slide back.

* NOTE that the GSG Firefly is a copy of the Sig Sauer 22lr Mosquito pistol. The parts on the Mosquito are interchangeable with the GSG Firefly. So no matter if you are buying Sig Mosquito parts or GSG Firefly parts, they will fit both guns.
