This guide details the installation of the CSRG Competition Follower & Spring Kit into a Staccato G3 20-round magazine, enabling a capacity increase to 24 rounds.

It's noted that this modification results in the magazine no longer locking the slide back on an empty chamber, making it a specialized tool for competition or specific concealed carry setups. Instruction is provided by TallShotTony, an active competition shooter with demonstrated technical proficiency.
