Tyrant CNC S&W M&P Full-Size Magazine Extension +5 – Black

The Tyrant CNC Magazine Extension adds five rounds to your standard S&W M&P full-size 9mm magazine, increasing capacity from 17 to 22 rounds. This extension provides a substantial firearm capacity boost for competition shooters, range training, or home defense applications where higher round counts matter. The added baseplate length also improves grip purchase during reloads.

Machined from 6061-T6 aluminum with a Type III hard anodized finish, this extension installs without permanent modification to your factory magazine. Installation requires disassembly of the factory baseplate, insertion of the included extended spring, and attachment of the Tyrant baseplate—no gunsmithing required, though familiarity with magazine disassembly is recommended. The knurled texture on the baseplate provides secure handling during magazine changes.
