    Product Description

    The Mk 1 Apex Grade Semi Drop-In 4.25" Barrel is designed for the 9mm Smith & Wesson M&P. Due to the tolerance variations in the M&P Slide, the barrel is semi drop-in. In some cases this means the barrel may drop-in without alteration, but in most cases will likely require minor fitting which is easily done by the end user. 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 1-1/2 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.

    Expected Results

    • Direct replacement of factory 4.25" barrel
    • Improves accuracy
    • Optimal performance seen with bullet weights of 115gr. through 147gr. using 9mm jacketed ammunition
    • Due to variations in factory slide tolerances, slight fitting may be required and is easily performed by the end user

    Applicable To What Gun(s)

    • Works with all Smith & Wesson 9mm M&P pistols, including the M&P M2.0, requiring a 4.25” barrel.

    In The Package

    • 1 ea. Mk 1 Apex Grade 9mm Semi Drop-In Barrel - 4.25"
