TANDEMKROSS Maximus Plus 1 Follower Features The TandemKross Maximus Plus 1 Follower is a simple drop-in upgrade that lets a Ruger Mark Series magazine hold 11 rounds instead of the standard 10 giving competitors an edge in matches that permit an extra starting round. Built from durable Zytel the follower is engineered to hold up through thousands of rounds cycling across magazine after magazine without losing its shape or function. The bright red color is a deliberate safety feature making it immediately obvious from a glance down the magazine well when the gun has run dry. No special tools are required for installation since the follower simply replaces the OEM factory follower already in the magazine. Compatible with the Ruger Mark IV Mark III Mark II and 22/45 pistols this follower works with both the factory magazine base pad and TandemKross s own MarkPRO Magazine Bumper accessories. Each package ships with two followers giving enough to upgrade a pair of magazines in one purchase. TandemKross notes that pairing the Maximus Plus 1 Follower with their Plus 1 Base Pad does not stack to 12 rounds capping total capacity at 11 regardless of which extended bumper is used. For competitive rimfire shooters looking for every legal advantage in capacity and faster follow-up visibility on an empty magazine this follower is a low-cost high-value upgrade.
