The TTI 4mm Magazine Extension is a mid-profile basepad built for 2011 style magazines chambered in 9mm/38. It adds two rounds to a 20-round magazine, bringing capacity to 22 rounds while keeping the assembly within USPSA 140mm gauge specifications, so competitive shooters can carry more rounds without falling outside equipment rules.

It is compatible with Staccato, Infinity, Springfield Prodigy, and Atlas 2011 magazines, and works with the factory spring and follower. The hard coat anodized blue finish gives the basepad a durable, competition-ready look.
