A 13 round magazine upgrade kit (+3) for the factory Ruger SR22 10 round magazine from Taylor Tactical Supply (TTS).
When fitted the follower replaces the thumb assist on the magazine. This removes last round hold open functionality (powered by the thumb assist) but replaces it partially by locking the magazine back against the follower on empty.
The slide lock can be deployed manually if needed. Magazines will not drop free unaided, unless the slide lock is operated, but can be easily pulled free.
Includes:
- Replacement follower
- Replacement locking plate
- Extra power spring
