Warne 3011 +4 Magazine Extension for Archon Type B / CZ 75
Add capacity and a more positive gripping surface to compatible 9mm magazines. Warne part 3011 is the black, nominal +4 magazine extension for the CZ 75 pattern and is offered by Rain6 for compatible Archon Type B and Strike One magazine setups.
Rain6 Capacity Recommendation
The extension body is rated for a nominal +4 rounds in 9mm. When using stock magazine springs, Rain6 recommends loading +2–3 rounds to maintain stronger spring pressure and support reliable feeding and slide-lock function. Actual usable capacity can vary with the magazine body, follower, spring condition, and spring configuration. Function-test every completed magazine before relying on it for competition, carry, or defensive use.
