Presenting….The Apex Reset Assist Mechanism

Los Osos, CA

Apex Tactical Specialties, Inc. (ATS) announces the release of the newest addition to its growing line of high quality drop-in parts for the Smith & Wesson M&P pistol line; the Reset Assist Mechanism (RAM). The RAM, which can be easily installed without the need for special tools, takes the M&P to new levels of shootability by producing a positive tactile sense of trigger reset that alerts the shooter that the trigger is past the reset point and ready to fire again.

“Improving the reset feel of the M&P trigger has been a major goal for us at Apex. The new Reset Assist Mechanism we developed gives shooters that positive, tactile feedback they look for in a trigger. This is particularly important to tactical and competition shooters who rely on a positive reset feel to help guide their trigger manipulation, especially during rapid fire situations,” said Randy Lee, president of Apex Tactical Specialties and designer of the RAM.

Additionally, the patent pending design of the RAM functions as a fail-safe device in the event of a Trigger Return Spring breakage. The RAM maintains trigger bar alignment under the Sear, allowing the shooter to manually reset the trigger between shots in the event of an emergency.

“Because so many of our customers are in law enforcement, where the M&P pistol is in wide and growing use as a standard issue duty sidearm, when presented with the opportunity to engineer the RAM to provide a fail-safe in the event of return spring breakage, we jumped on it. Increasing the reliability of an already reliable pistol is a win-win no matter who you are,” explained Lee.
Made in the USA from the best materials and to Apex’s exacting standards, the RAM is available for Smith & Wesson M&P pistols that do not include a thumb safety and are chambered in 9mm, .40S&W or .357SIG. Models for thumb safety equipped pistols and the .45ACP models are in development.

  2. R Grey Van Ingen - November 3, 2010 @ 12:53 pm

    Is There an install tutorial?

    My M&P .40 came with the internal lock and I do not use it. I know you said that the RAM could not be used with a gun that has the internal lock installed.
    Is there any way that the lock can be removed so that the RAM can be installed?

  5. SGB - November 6, 2010 @ 11:47 am

    WOW ………. talk about making a difference. AAA+

    How long until you get the RAM for the .45 full sized with manual safety? I have the ‘california gun’, so it has a mag safety but no internal lock.

  7. scott - December 1, 2010 @ 5:03 pm

    We’re still working on the designs, we don’t have a release date set as of this time.

    I have an M&P 9mm compact with MAGAZINE safety but NO internal lock and NO manual safety.
    Can I install the RAM in this pistol?

  9. David NYC - February 11, 2011 @ 5:23 pm

    any luck with the ram for safety models yet?

  10. scott - February 11, 2011 @ 10:55 pm

    The RAM for the Mag Disconnect models is online and available. Make sure you get the right one when you order though.

  11. David NYC - February 20, 2011 @ 10:03 pm

    Im sorry I meant the thumb safety model.

  12. Brett - March 8, 2011 @ 8:14 pm

    Any ETA on the RAM for the thumb safety M&P 40c’s?

  13. Dave - September 16, 2011 @ 9:51 am

    Any update on potential availability for a RAM compatible with safety models?

  14. scott - September 18, 2011 @ 7:59 am


    We’re working on the Universal RAM, we do not have any further information at this time.

    Does this work in M&P performance center 9l SKU 10218

  18. paul - July 20, 2018 @ 7:54 am

    If it is an ILS frame.

    I just installed the RAM into my 40c already upgraded with APEX duty/carry kit and aluminum trigger. Gun functions well and I can hear a click (without ear protection) at the reset point, but I cannot feel it. I guess I was expecting a result similar to my 2.0 Shield. Assembly was easy. Does this sound correct?

  20. scott - February 18, 2019 @ 6:24 am

    That does sound correct. The Shield trigger bar has a large dimple on the inside that presses against the frame near the front of the trigger bar, forcing the trigger to pop over in a different way and create more of an audible and felt reset.

    You could try making sure your trigger bar loop is parallel to the end of the trigger bar below it. IF you tweak it slightly toward the sear itself, you will notice the reset seems better too.
