PCC base pads extend magazine capacity for Glock-pattern pistol caliber carbine magazines used across CMMG, KelTec, and PSA PCC platforms, plus dedicated PCC-specific magazine extensions built for the division's fast, high-round-count stages. PCC has become one of the fastest-growing USPSA divisions, and stage design often rewards shooters who can run more rounds per magazine without sacrificing reload speed, making base pad selection a real factor in PCC gun setup. TTI and Lancer extensions cover both true Glock-pattern PCC magazines used in CMMG Banshee, KelTec Sub2000, and PSA PCC builds, as well as extensions built specifically for dedicated PCC magazine bodies. Extended base pads add meaningful capacity within division rules while improving reload speed under recoil-free carbine handling, where a longer gripping surface helps the support hand seat the magazine quickly during fast stage transitions. Shooters should confirm their specific magazine body - true Glock-pattern versus dedicated PCC pattern - before selecting an extension, since fitment differs between the two.
