With the HiCap +4 (Plus 4) follower you can turn your factory 10 round Sig Mosquito magazines into a 14 Round Magazine. With one (1) round in the chamber and 14 in the magazine, that's 15 in the gun! The shorter follower allows for more space in the magazine tube so that it will fit an additional four (4) rounds in the mag.

PLEASE READ BEFORE PLACING YOUR ORDER
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.

3 of 5 Mosquito magazine upgrade March 19, 2024
Reviewer: Mark Bunn from Anderson, MO United States  
Had too sand down the rounded front of all followers & the square backs along w/just a tad on sides too allow for a smooth function up & down and not get stuck ... flawless function afterwards ...

5 of 5 Great upgrade to any Mosquito November 8, 2022
Reviewer: RonS. from Summerville, SC United States  
I was trying to decide what to do about the low capacity of my Mosquito,  sell it off and buy one of the newer hi capacity 22 pistols currently on the market or ? Well looking for higher capacity options brought me to a video showing these great followers.  With these I was reasonably able to meet my higher capacity wants but not spend hundreds more on a new pistol. These were easy to install, work great, and are a quality upgrade.
