Dry Fire Training Magazine for Glock 9mm,357,22,40,45 - Light Weight, Dry shooting training system with audible & tactile trigger simulation, NOT Compatible with10mm /.45 Cal or Laser Cartridges

I had to return the first one I ordered and exchange it. For some reason or other, the first one didn't fit quite right for the click mechanism to reset the trigger.The replacement works beautifully. I use thus in conjunction with the Mantis X trainer. Very nice.

The product works as advertised. I didn’t realize that it would not activate the firing pin of the gun, so it could not be used with a laser cartridge. It functioned as it was supposed to, I just didn’t do enough research before purchasing. Will still be used for dry fire practice.

In an effort to figure out if various dry fire mag systems would add any value to my training, and if so, which one provided the most value, I bought 4 systems including this one.Things I bought to compare:[DFM]DryFireMag: https://www.amazon.com/dp/B07JR1Q4ZM?ref=ppx_yo2ov_dt_b_product_details&th=1[TTM]TTrigger mag: https://www.amazon.com/dp/B0BRKVT7ZR?psc=1&ref=ppx_yo2ov_dt_b_product_details[SSS]SureStrike System(Smart DryFire Mag + SureStrike Laser Cart): https://www.amazon.com/dp/B0CP69ZV1W?ref=ppx_yo2ov_dt_b_product_details&th=1[BOS] BlueOps system (2 xmags, 1 xLSR): https://www.amazon.com/dp/B0D1DHTNQM?psc=1&ref=ppx_yo2ov_dt_b_product_detailsI think when considering any of these systems, the first question to ask yourself is whether the $100(or more) for a convenience that allows you to pull the trigger multiple times without resetting the slide is worth it to you. It may be tough to justify, but I think the ability to practice transitions and follow-up shots as if you were shooting live-fire is more than worth the up-front cost. Just for fun, here's some math:Let's assume that in terms of training effectiveness, 4 dry-fire rep is worth 1 live-fire rep. I think this estimate is very conservative but for the sake of argument, lets run with it. Keep in mind, Dry-fire is not a substitute for live-fire, but rather a supplement.With the assumption of 4Dry:1Live, this product would "break even" after 1667 reps([product cost]/[cost per round]*[training effectiveness ratio] = [$100]/[$0.24/round]*[4:1 effectiveness]=1666.66667). So, the question is before you lose or break this system, do you think you'll use it to simulate more than 1700 shots? That's an average of less than 5 shots per day over the course of a year, or less than 17 shots per week over the course of 2 years. I think it's more than worth the cost to add a system like this to the training regimen.The TTrigger mag performed fine, but I can't find an argument to purchase it over the competition. The DryFireMag system is the original magazine-based trigger reset system(AFAIK) and has been available for longer, has a slightly more realistic trigger feel, supports more weapon platforms, seems to be built better with more durable materials, and has a more accurate weight. I can't find a good reason to purchase this system compared to the competition. At the time of this review, the DFM is around $5 less than this TTM system, and the DFM with additional springs for adjusting pre-travel weight is just $5 more. I would recommend the DFM system over the TTM due to the factors noted above.Now to review the TTM on it's own merits.Strengths:+ Simple system that uses a lip on the "magazine" to reset and provide resistance to the trigger by indexing on a nub on the trigger bar. It works+ The "magazine" provides adjustment to the pre-travel resistance through 4 additional springs and adjustment to pre-travel distance/break location through a set screw at the rear of the mag. This system also works.+ Blue color makes it easy to identify the mag as a training tool from the magwell of the weapon)easily identifiable by the oversized baseplate) and by retracting the slide. I like this for safety reasons.Weaknesses:- My trigger may have excessive drag, but the lighter springs caused the trigger to occasionally get bound up on reset. This was true on multiple firearms I tested with. I would stick with the stock spring that comes installed and forget about the notion of adjusting trigger weight with this system.- as mentioned above, the included springs modify the pre-travel resistance but does nothing to the break weight. The "break" is determined by a separate mechanism(likely a dome spring) housed within the mag itself. There is no adjustment of the feel or weight of the break. (This is true of all 4 systems I tested)-Overall light and cheap feel of the magazine makes me question build quality and long-term durabilityTLDR: I think that dry-fire training tools like this one are more than worth it for shooters willing to put in the effort to train regularly and understand the limitations. However, I don't think that this particular system is worth the cost when a more thoroughly tested and seemingly higher quality alternative exists through the DFM system.

I'm a cop and she's a firearms instructor. This is a VERY useful tool. Very expensive for what it is and probably cost $5 or less to make but unless you are going to take a magazine, destroy it, and try to engineer this thing on your own?...Just buy this one.

well built

The feedback you receive from this device is fantastic. No longer do you need to rack the slide in order to cycle the action to dry fire. Simply insert the magazine, press the trigger rearward until the shot breaks. Reset is totally automatic with this training magazine installed, no need to rack the slide after the initial setup. Continue dry firing until your heart is content, all while gathering front sight feedback on the shot in real time, every time. This device allows you to learn what happens when the shot cycles and helps the shooter tweak their grip and improve trigger pull to reinforce what works for the individual. This quickly reveals both strengths and short comings within shot strings helping reinforce proper technique that can improve hand placement, grip pressure and trigger press. Side note - read and follow the instructions. I assumed that changing the spring to raise or lower trigger pull weights would be simple, and it was, but it did get away once, bounced across the room to be recovered by the cat. Make sure you put on glasses as they suggest, (those shown are not included, they're mine) just to keep you safe. In summary, this device is worth every penny and then some. All 5 stars land here. Where's the 6th one? I'd award it.

I did a lot of research to try to figure out what this was and how it differed from its main competitor. At the end of it all, I couldn't find any real difference. So what is this? It's an attempted solution for dry firing a pistol, specifically the described Glock models. After doing your safety checks, you slide this in, squeeze the trigger for a real pull, then subsequent squeezes are simulated/actuated by the spring mechanism in this magazine. I have a mostly stock 19, just a polished trigger bar, otherwise no aftermarket items. I haven't tuned my dry fire mag yet, but it is noticeably different from my regular pull. The reset is also much shorter. So it looks like I'll need to spend a lot of time tuning the magazine to get closer to my real pull. In the meantime though, I guess it work? It does let you squeeze the trigger sequentially without needing to pull back the slide each time. The other issue is combining it with a laser round of some sort that reacts to sound or you can use the Mantis system (that's probably my next purchase). For now, it's better than nothing for dry fire practice at home, but it's not ideal on its own and will need tuning to better match your real pull.
