Observations:

The first thing i noticed, right away...it looks cool on the pistol. At least to me.

When first aiming my P7 with the Fastfire, trying to acquire the little dot in that tiny little glass "HUD" window is not easy. I boresighted it and have been practicing with presenting the weapon from draws, and i am much better at it now. But it is definitely an acquired skill. I suspect once i practice it sufficiently, and get in some range time, i will be very happy indeed.

I think that this could actually be very useful if someone ever tried to use your weapon on you should you somehow be disarmed. For someone not accustomed, they'd have a devil of a time hitting any kind of a fast moving target...

However, i can already tell that it's much faster(when you present correctly) and more precise than regular iron sights.

Acquiring the reticle from odd angles is even trickier, but i am already getting better at that too in just a couple days of fiddling with it. I suspect that it will take about a half dozen range trips and a few months of practice draws and movement to really get proficient with it. It forces you to present the same way, every time, with a good, sound hold on the pistol. So in other words, it is training really good habits.

The Fastfire has an auto reticle brightness feature.

In bright light to moderate light the dot is really bright and super easy to see- even in broad daylight, even aiming at snow in broad daylight. Precision close-medium range shooting should be no problem.

At low light to me the dot gets too dim, i can still see it and all, but IMO in low light conditions it's always about 10-20% too dark. There is a light sensor on the front of the sight, i'm fixing to affix a tritium capsule there and default the thing to max bright, lol. I don't think there's any user adjustment you can make, so i'll probably just have to get used to the night brightness levels and live with it. It's still way better than conventional iron sights, and would be just fine for precision shooting, but it's a bit too dim IMO for super-rapid target acquisition.

That's my only real complaint, and others might not even agree.

Oh...the fastfire has a manual on/off switch, but the battery lasts 5 years in on mode. I noticed that i was hitting the tiny switch off by accident when racking the slide, so i super glued that sucker to the on position. It was way to easy to accidentally turn it off. Now it's like a Docter or Trijicon MFD- always on.

If i was a cop or soldier carrying a Fastfire in a duty holster where it would get knocked around a lot i would tape over the switch too. (The fastfire is supposed to withstand 1000g of slide cycling energy)
