PEORIA, Ariz. – Apex Tactical Specialties announces the expansion of its line of patent pending Apex Grade Barrels for the Smith & Wesson M&P with the upcoming availability of Apex Grade 40/9 Conversion Barrels in Semi Drop-In and Gunsmith Fit configurations. Designed by Apex founder and CEO Randy Lee, the unique barrel geometry of the Apex Grade Barrels consistently delivers five-shot groups well under two inches at 25 yards, whether it is with 115gr., 124gr. or 147gr. factory ammunition. In controlled testing using a Ransom Rest that eliminates the human element and focuses only on the mechanical operation of the barrel in the dynamic environment of the functioning pistol, Apex Grade Barrels routinely delivered sub-one inch groups with several under one half inch. The new stainless steel Apex Grade Conversion Barrels feature a 1:10” twist rate and are chambered in 9mm and designed for use in .40S&W M&P pistols with 4.25” and 5.00” length standard barrels. The Apex Grade Semi Drop-In 40/9 Conversion Barrel can be easily fitted by the end user and is designed to significantly increase accuracy performance, making the M&P capable of shooting a one and a half inch or better grouping at 25 yards. The Apex Grade Gunsmith Fit 40/9 Conversion Barrel is designed for installation by a trained gunsmith who can perform an exact barrel fitting to a specific pistol. This precision approach to fitting makes the M&P capable of shooting a one inch or better grouping at 25 yards. Final accuracy results after installation may vary based on the individual shooter’s ability, ammunition selection and variations in factory firearm tolerances. Additionally, as with all conversion barrels, the shooter may experience erratic ejection patterns due to light or low velocity rounds. The new Apex Grade 40/9 Conversion Barrels for the .40S&W Smith & Wesson M&P retail for $199.95 and will be available through Brownells as well as direct from starting Tuesday, February 28.
