This popped up on my suggestions on Amazon, anyone have it or used it? Looks interesting for dry-fire practice.

My son-in-law gave me one for Christmas. I've used it a bit and, I think, it's actually quite useful. You can easily tell if your hold and trigger discipline are faulty.

The only downside for me is that its designed to mount on a rail or use an adapter. I've used it on my G19 but all of my Sigs require the adapter that mounts on the magazine. I haven't tried that yet

I've seen something like that on a rifle.
It showed the guys pattern of getting on target. He was able to learn to confine his movements. Did it help anything ? Idk.
I think it's a fun toy that helps me think I was some how improving my abilities. But ....is it ?

The Amazon reviews are overwhelmingly positive. But it's hard to know whether these are people who know much about guns or shooting. I'm very interested in seeing responses from those in this forum.

I bought one for my son for Christmas.

He immediately broke his wrist and couldn't use it.

I've got one that my wife's used quite a bit and it's helped her.

I've yet to try it, but would like to, for dry fire. I'm just not sure if it actually works, and I've been making good progress with current dry fire training, and I'm not sure I want to drop $160 to test this out. A few years back I got a SIRT pistol. It's a great idea in theory, but it's next to impossible to adjust the trigger to anything useful, and you need to put on real sights, for an added expense. So I'm worried this is another good idea In theory, but not in real use.

In general being able to place an objective measure on performance is a good thing. If you're actually tracking your hits/misses during live fire you have an objective measure of performance (http://pistol-training.com/archives/9464). In theory this gives you an objective measure during dry fire, and if it really works as advertised it might be a good tool.

I have not tried that but for dry fire I prefer something like the LaserLyte 9MM trainer cartridge. With that I get instant feedback with a very brief red laser dot and I don't need to use any other device. It is also helpful for practicing point shooting.

I have one and find it to be useful for both dry firing and live fire. Mostly I use it for dry fire. Lately I have been carrying revolvers and I don't think there are any adaptors for revolvers.

I primarily used it for dry firing my Colt Wiley Clapp Lightweight Commander. Big difference between dry fire use and live fire use. Oh, it works well. I'm the one that doesn't do nearly as well.

Just got one, very cool!

I have one. I use it mostly for dry fire (which regardless I do not do enough.) That said, I want to break it out in live fire mode the next time I'm trying B8s at 25m to see WTF I'm doing.

Great, now there's (yet) another gizmo my minibrain says I need.....
