A spare follower for the TTS .22LR magazine upgrade kits for Walther PPQ, P22 and PPK/S pistols.
- Increases Walther PPQ magazine capacity to 15 rounds
- Increases Walther P22 P22Q P22D SP22 PPK PPK/S magazine capacity to 13 rounds
- Operates last round hold open by blocking the slide
This requires the larger box spring provided in the upgrade kit to work, will not work with the Walther factory magazine coil spring.
