Stable, well-defined dot (even for old eyes) - Burris FastFire C 1x22mm Red Dot Reflex Sight

I am an old-timer (real years and red-dot years), having bought an Aimpoint (stupid heavy and big) way back when. That cured me of holographic sights for sometime, but aging eyes made me try again, with Burris Fastfire--not this one, the previous ones. More recently, the Vortex Defender CCW, much tougher than the flimsy Fastfires. All my prior dots were somewhere around 3 moa, so I was wary of a 6 moa dot, but this C not only looked tough, it also fit directly on my new P322. And the price was right. Turned out to be so good, I moved it to my Buck Mark (replacing a not-too-bad Crimson Trace). The "always on" tech beats the "shake awake" by a country mile. The dot is certainly good out to 15 or 20 meters (the distance I shoot pistols). Windage/elevation screws use a very small flat screwdriver, and work OK. Have not had trouble with inadvertent settings change. Although I want tritium iron sights for EDC and bedside, this is the only dot I would use at the range. One gripe: the glass is not receded enough at the front (Burris should look at the Vortex Defender) so it gets smudged too easily.
