Frequently Asked Questions
The DFM resets the trigger in your striker-fired pistol, so you can dry-fire practice without racking the slide between trigger pulls. Therefore, the practice does not instill the dangerous muscle memory of racking the slide between rounds.
No. The DFM does not use the firing pin, because all the mechanism is contained within the body of the mag. The DFM only interacts with the trigger bar.
The DFM is designed to simulate at least a partially loaded magazine, no heavier.
No, because the lever that interacts with the trigger bar is a softer material than the trigger bar. Any wear would take place on the DFM lever and not on the trigger mechanism.
None at this time.
The DFM works fine with most performance triggers (Apex, Zev, Powder River, etc.). The DFM is easily adjusted to accommodate the “break-point” of custom triggers. With the addition of the optional Spring Pak, the DFM easily adapts to most custom trigger-pull weights.
Yes. With the adjustments that are available with the DFM, we are able to duplicate most trigger systems.
It depends on your gun’s frame size. Most DFM models are designed to fit the makers’ standard or full-size model. If you have a compact, or subcompact model; the DFM can still operate with your firearm though it may protrude past the gun grip.
The Spring Pak allows you to tune your DFM’s trigger weight just the way you want it, or to the specs your academy or department requires. Check out the product details to see the trigger weights achievable with each spring in the kit. There is currently a kit for Glock DFMs and the S&W M&P DFM. Of course you are free to do what you like with the springs in any kit, with any DFM that will accept a spring.
The DFM can be finely adjusted to replicate most pistol trigger systems. Instructions are included in the package and can be found HERE. If you need further assistance, you may call DryFireMag Tech Support at 844-844-4240.
No. The DFM will not free fall from the magazine well because it has to interact with the trigger mechanism. It must be stripped from the pistol. Stripping and throwing the DFM onto hard surfaces could damage the DFM.
Our policy is to ship the next business day after the order is placed (Monday thru Friday). If ordered from DryFireMag.com, you will receive your DFM as fast as, if not faster than Amazon Prime delivery unless there are US postal delays.
This is not yet determined. We have had units being used for 5+ years by some of our customers who do thousands of reps per week, and they are still going. It is warranted against defect for 1 year.
Yes. There is a 30 day period to try the DFM.
The DFM comes with a one-year part and mechanism warranty. You will need to fill out this form for the warranty to be honored. We will need your name and
the email address that you used to order, or the order number from dryfiremag.com.

DryFireMag does not guarantee the MantisX system will work with the DryFireMag for the simple reason that it is not our product. However, we have found this to be a great training combination.
For best results remove the DryFireMag baseplate and replace it with the MantisX mag rail. This will ensure that the Mantis product is as close as possible to be activated by the audible reset of the DryFireMag.
The following floor plate rail adapter works with all of the current DryFireMags:
MagRail – Glock Double Stack 9mm/.40 – Magazine Floor Plate Rail Adapter
Use these settings in the MantisX app for better results:
Gun Type = Pistol
Mount Direction = Backward
Mount Location = Bottom
Trace, View Auto Zoom = OFF
Bullseye Mode = OFF
Sensitivity = HIGH
Detection Delay = ON
Practice = DRY

Most DFM models are designed to fit the makers’ standard or full-size model. If you have a compact, or subcompact model; your DFM can be “seated” correctly even though it is protruding past the gun grip. If your mag-release has popped fully out, and you are unable to pull the DFM back out without pressing the mag-release; then your DFM is in as far as it should go.
It’s likely that either the wrong mag was ordered, or we inadvertently shipped the wrong mag.
Please contact us with the make and model of your firearm and report the model DFM stamped on the DFM box that you received so we can get it “ironed out”.
This is usually an indicator that some trigger modifications were made to your firearm, or you
have an OEM modified version of their standard model. If you do not see an adjustment recommendation below for your situation, please contact Tech Support:
Phone: 844-844-4240
Email: techsupport@dryfiremag.com
To make adjustments, you will need the enclosed Allen wrench in order to adjust the Set Screw
through the port of your DFM. You should also have a way to record your adjustments in case
you are unsuccessful and need further assistance. (Your DFM should be returned to its factory
settings before calling tech support for the highest probability of success with the technician).
If the recommended adjustment fails to work, please contact Tech Support:

Over adjustments can
cause damage.
- Glock with Apex trigger system: 1/4 Clock-Wise turn
- Smith & Wesson Performance model with Apex trigger: 11/4 Clock-Wise turn
- Smith & Wesson M&P 1 with Apex trigger: 2 1/2 Clock-Wise turn
- Springfield XD with Powder River custom trigger: 11/4 Clock-Wise turn
- Springfield XD mod2: 1/4 Clock-Wise turn
- Springfield XD 40 cal: 1/3 – 5/12 (12 O’clock to 5 O’clock position) Clock-Wise turn
- Sig P320: The Sig P320 mag (DFM P9) may require extra-fine adjustments due to the Sig
P320’s unique FCU design and the myriad of popular customizations available, particularly
custom triggers and grips which can both make the need for adjustment necessary.
Please follow the protocol below:
With the “hour” positions of a clock in mind, try turning the Set Screw clockwise first, moving
only 1 hour at a time, testing between each adjustment. You can likely only go as far as from 12
O’Clock to 9 O’Clock before tripping the internal leaf spring, in which case, you’ve definitely
gone too far. Most often, the correct position will be located within a 1/4 turn from factory (or
from 12 O’clock to 3 O’clock, or 12 O’clock back to 9 O’clock). Listen closely as you make each
adjustment for a “click” sound from inside the mag. If you hear a “click”, you have gone too far
and must back off. The “sweet spot” can be a very narrow range. Most people miss it by
making too large of adjustments at once.
If going clockwise doesn’t cut it, return the Set Screw to its original position and try going CCW,
using the same routine.
Most likely only a very slight adjustment is required to make your DFM feel just right. Very slight adjustments can make “a world of difference”. If you need assistance getting your DFM adjusted properly, please contact Tech Support:

If you have the Mantis10, make sure your app is configured such that the
Shot Detection Mode = SIRT/DFM.
For earlier versions: set the Detection Sensitivity = HIGH, Detection Delay = ON
(~0.7 seconds works well to avoid trigger reset detection), Practice = DRY
