Apex Announces 9mm M&P Barrels

LOS OSOS, Calif. – Apex Tactical Specialties, best known for their aftermarket upgrades for the Smith & Wesson M&P line of pistols, announced the upcoming release of their newest product, the Apex Grade 9mm Semi Drop-In and Gunsmith Fit Barrels for the M&P.

Since its introduction the Smith & Wesson M&P has experienced accuracy issues with owners frequently reporting only adequate to mediocre accuracy, and often at just 10 yards. Fine for a polymer frame striker-fired combat pistol, but less so for a competition firearm. For the past four years, Randy Lee, one of the industry’s top design engineers and the president and CEO of Apex, has been working on improving the M&P’s accuracy. The result is the unique Apex barrel geometry, included in the company’s patent pending barrel design, that consistently delivers five-shot groups well under two inches at 25 yards, whether it is with 115gr., 124gr. or 147gr. factory ammunition.

ApexGrade-1In 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, the new Apex Grade Barrel routinely delivered sub-one inch groups with several under one half inch.

When tested at the extreme of 50 yards, the 5.00” Apex Grade Barrel, shooting 147gr. factory ammunition, delivered a 1.86” five-shot group (measured center to center), putting it on a par with high-end custom built 1911 pistols. By comparison, the same test pistol shot with the Smith & Wesson factory barrel delivered a 5.209” group, nearly three times larger than that of the Apex Grade Barrel.

“After four years of chasing accuracy in the M&P, we are very pleased to introduce our Apex Grade barrel design which doesn’t just improve the pistol’s accuracy but far exceeds that of any aftermarket barrel currently offered,” said Randy Lee.

“Through extensive research and testing we were able to pinpoint the causes of the M&P’s errant accuracy and address them with a proprietary Apex geometry that takes into account the wide range of varying tolerances found from one M&P to another. With either our Apex Grade Semi Drop-In or Gunsmith Fit Barrel, customers can finally get the accuracy they have been chasing in their M&P.”

The new stainless steel Apex Grade Barrels feature a 1:10” twist rate and will be available in 4.25” and 5.00” lengths in either a semi drop-in or gunsmith fit configuration. The Apex Grade Semi Drop-In 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 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.

Apex will offer installation and fitting of the Apex Grade Gunsmith Fit Barrel as part of their wide range of gunsmithing services. Customers interested in having their M&P worked on should contact Apex Customer Service at (805) 528-5250 for a quote.

    No, only the M&P and M&P M2.0.

    I would like an M&P Shield 9mm extended barrel – 4.17″ – for canadians – so we can have the M&P Shield up here too!

  3. Mike Mc - February 21, 2018 @ 7:39 pm

    Everyone is looking for an extended shield barrel. Do you for see ever producing such a product?

  4. paul - February 22, 2018 @ 11:49 am

    Not at the moment.

  5. Dan Moore - March 6, 2018 @ 6:33 am

    Can a 5 inch barrel be used in a gun with a 4 1/4 inch barrel?

  6. paul - March 12, 2018 @ 8:41 am

    No, it will not fit properly at the muzzle.

  7. Kenneth White - May 20, 2018 @ 4:34 pm

    Can you fit for a SW MP9 Core … Performance model? For Gunsmith fit does it have to be sent to you and how long is the turn around? I am toying with the idea of using my MP9 for CMP service pistol.

  8. paul - June 25, 2018 @ 8:00 am

    Yes, our 9mm barrels for the M&P will work in your M&P9 C.O.R.E. model. You can install the gunsmith fit barrel yourself but we recommend that you get our barrel fitting jig to assist in the installation. It will help you keep the file in the correct position when filing the rear bottom fitting pad. You can also send it to Apex to install it for free, assuming you buy the barrel direct from Apex between May 1, 2018 and Aug. 31, 2018. Further info is posted here on the blog.

    Any plans to have a limited run for extended shield barrels, why not test the waters and see how many would want one?

  10. paul - December 10, 2018 @ 2:27 pm

    No plans at the moment.

  11. RightWing_LeftCoaster - January 28, 2019 @ 1:55 pm

    I also want a long barreled Shield…I like the slim profile, I like the accuracy, and I prefer the sound pressure of a Full length barrel, it is quieter…also, I think it would look like a SPACE LUGER!!! Call it an m&p SPACE FORCE LUGER KIT and they will sell like hot cakes. 1/2×28 on the end please.
    Quiet a bit of interest on forums. Others have tried to modify different barrels to achieve this functionality, but the feed ramp angle in the shield, is unique…or so I’ve read.

    If I send my M&P C.O.R.E. with 5″ barrel to you for installation of a new 5″ barrel do you need just the slide or the whole pistol? I installed your trigger, hardened slide, etc. previously. Does that make any difference?

  13. paul - March 14, 2019 @ 1:37 pm

    Unfortunately we are not currently taking in guns – or slides – for barrel fitting at this time.
