What It Does
The Mk 1 Apex Grade Threaded Gunsmith Fit 5.00" Barrel is designed for the 9mm Smith & Wesson M&P. The barrel is NOT drop-in and requires fitting by a competent gunsmith. The stainless steel barrel features a 1:10” twist rate. The design increases accuracy performance making the M&P capable of shooting as small as a 1-inch grouping at 25 yards. Accuracy test results based on use of a mechanical rest. Final results may vary based on shooter ability, ammunition selection and variations in factory firearm tolerances.
