The Apex Tactical Apex Grade semi drop in conversion barrels are specifically designed to drop into most S&W M&P40 full size models. Due to the tolerance variations in the M&P Slide you might be required to perform some minor fitting of the barrel to the slide. By placing this barrel in the slide of your M&P you have taken your first step into being able to shoot 9mm Luger out of your M&P40. The barrel is made from stainless steel and features a natural finish. During testing using a mechanical rest it was discovered that the barrel was capable of 1.5" groups at 25 yards. Your results may vary based on shooter ability, ammunition selection or variations in the factory firearm's tolerances.
