Part of the TF "Competition" line, the "Triple Threat" basepad brings the suggestions of countless competitors into one multi-purpose design. - WILL NOT hook another magazine, or snag on your clothing (and come out of the mag pouch) as you move. - Extends the magazine to ensure a positive reload at speed - Provides one ounce of extra weight, helping with recoil control (still legal for IDPA and USPSA matches). - Works with BOTH styles of M&P magazine. (Square- or round-hole.) NOTE: Works with all known magwells, including the SSS and Carver Custom lines. Available in black, bright (zombie) green, lavender, more.
