Thanks for the feedback, guys!
Triad,
Actually, it's an XD9 in the picture, which explains the hex screw. It's part of the cover that holds the cocking indicator and the firing pin assembly, I think.
SouthpawShootr,
there is a night sighted version in the works. It takes a lot longer than I'd like it to, since the NRC (Nuclear Regulatory Commission) must approve each new sight design, and for something that's markedly different than a standard sight--like the SureSight--it will probably be a while.
As far as a low profile, the front sight is actually taller than most standard sights, but because it tapers to a point, I have not yet found a holster that does not fit it. Also, though they don't look it, they really are snag resistant. I designed them with angles that make it virtually impossible for them to get hung up on clothing, holsters, etc.
My goal in designing them was to make a usable set of sights for precision work that could be crudely aimed when the primary focus of your eye is on the threat, not the sights. Based on lots of research, and some experience, this is the overwhelming involuntary human response in a lethal force encounter.
While I believe them to be very good self defense sights, I have used them in competition, and for me (I'm biased, of course) they were a whole lot faster than 3-dot notch & post type sights.
