Sub-one-inch groups at 25 yards? Yes. The Apex Grade Gunsmith Fit Barrels set the standard for accuracy. When properly fitted to both the slide and the frame of the pistol, these barrels can deliver 1.00” – and under – 5-shot groups at 25 yards, assuming you do your part. These barrels feature a 1:10” twist rate along with Apex’s proprietary, patented locking geometry.

Apex Gunsmith Fit Barrels are the most accurate barrels for the M&P, hands down. Trusted by law enforcement and approved for duty use by multiple LE agencies nationwide.

IMPORTANT: If this barrel is being installed into a slide with a Loaded Chamber Indicator, you will also need to purchase and install the Apex No Profile Loaded Chamber Indicator Block or remove it altogether.

These barrels require fitting by a competent Gunsmith.
