I picked up a Dry Fire Mag about four months ago after having had it recommended to me by at least two friends who were using it. Before discussing it further, allow me to disclose that I purchased this item at full retail price with my own funds. This review is being done with no consideration from the company and I have no relationship with them apart from owning an example of their product.
They make several claims on their webpage, among them: no more racking the slide to reset the trigger, practice double taps, and pays for itself in ammo savings. I don’t know that my experience really matches up with all of their claims, but I will say that those claims may all be true for you, depending on your intended usage.
My dry fire regimen involves a lot of draws, and most of that from concealment. My usual work is 30-50 draws, each with a trigger press or a takeup of the slack, depending on my mood. I work with targets in my basement and a shot timer with a par time set. The dryfire magazine doesn’t really change that part of my routine, although it does reduce the amount of extra movement I have to engage in to reset the drill. Prior to the Dry Fire Mag, obviously I’d have to rack the slide to reset the trigger, and now I do not.
Where the Dry Fire Mag really shines is in working drills with more than one trigger press. Prior to me using it, I’d be just touching the trigger to simulate trigger presses. Now if I’m setting up a Bill Drill or any other drill I want to work on, I just run the drill. While the Dry Fire Mag doesn’t feel exactly like a stock trigger press, it certainly duplicates it closely enough for my purposes. You can also change out springs on the Dry Fire Mag to simulate a heavier or a lighter trigger. This will probably be especially useful to you if you have a competition gun with a lighter trigger press, or if your agency mandates a heavier trigger.
This isn’t to say that my experience with the Dry Fire Mag was 100% trouble free. After clearing the gun and inserting the Dry Fire Mag, the first trigger press is extra heavy, allowing for the fact that you have to run the striker and the Dry Fire Mag spring both for that first press. After that the only thing resetting your trigger is the Dry Fire Mag, and it is much closer to that normal trigger press. What I just told you is the theory, because for whatever reason, on my Gen 5 Glock 19, the striker wouldn’t fall on that first trigger press. So I have to press the trigger on an empty gun, push the trigger forward manually, and then insert the Dry Fire Mag. Not a big deal, but it was annoying when I first had to figure that part out.
I also know that Dry Fire Mag makes models for the S&W M&P and the Springfield XD, as well as the Glock. They may have more models forthcoming, but I have no specific knowledge of that. I also have no idea how well the other models work, having only tried it on a Glock.
I do know that despite the slight issue I have getting it going, it still works really well for me and my dryfire routine. I use that Dry Fire Mag about two or three times a week, whenever I set aside time to do my dryfire work. It has paid off real dividends for me on more complicated shooting strings and drills, because it has allowed me to practice them much more realistically than I could have before. I suppose if I were to assign a grade to this product, it’d be an A-, which is still pretty solid and handily beats my old high school GPA. Overall I would definitely recommend this product to you if you have a Glock and you want to work your dryfire more realistically.
