Tyrant Cnc Tdmpmagexfsblk Magazine Extension Fits S&W M&P Full-Size Black

The Tyrant CNC Magazine Extension for S&W M&P Full-Size pistols is a straightforward capacity upgrade designed to add 5 rounds to your factory magazines. Built from 6061 aluminum with a durable black finish, this extension gives you the extra rounds without sacrificing reliability. It's engineered specifically for the M&P 1.0 and 2.0 full-size frames—measure twice before ordering, because this one won't fit the Performance Center M&P9 2.0 Competitor or compact variants.

What sets this extension apart is Tyrant CNC's NoBak Spring Plunger Technology, a retention system that lets you disassemble and reassemble the extension repeatedly without weakening the attachment. The serrated sides aren't just for looks; they give you real purchase when you're running magazine changes under stress, whether at the range or in a competition. A 10% power spring comes included to ensure the rounds feed reliably with the added capacity.

At 48 grams, the extension itself adds minimal weight, and the aluminum construction means it'll handle thousands of rounds and gear changes without degradation. This is the kind of straightforward upgrade that works—no gimmicks, no surprises. If you run an M&P 9mm or .40 in full-size and want to squeeze out another five rounds per mag without swapping to aftermarket magazines, this extension earns its place on your duty or competition rig.
