CA-guy: Thanks for an honest report. Sounds like you're a very good shooter. Getting 4-inch groups at 7 yards from a P-3AT with factory sights is pretty impressive IMO! Sorry you don't get to carry it for its intended purpose. Maybe someday CA will wake up!
Flyer: You're exactly right! I'm just now starting to get feedback from those who have installed the P-Sight. Thus far, it's been very positive. I should have some user comments on the website soon.
Also, as far as the front sight, I agree that a square element would be best. However, the small amount of real estate available for the rear sight means it's very small, as noted by CA-guy, and in keeping with my desire to preserve the footprint of the pistol. Thus, there's not a lot of sight picture room left over. A square front element "blocking out" or covering the factory front triangle would be too big. I think the only way to do it would be to mill off the triangle and attach a small front blade. Feasible, but not easy.
While I do have a vested interest in saying this, I do find the sight picture with the P-Sight installed to be quite adequate. Enough daylight left and right of the front element to center and level it with ease:
G33: Like most if not all P-3AT's, mine, which was the guinea pig pistol, shot low at 5 yards. During testing, I mounted a P-Sight prototype onto my pistol by snugly fitting it into the rear sight cavity, then using a thin strip of masking tape around the back end of the slide, but above the hammer. It held the prototype in place very well. I then fired it, and incrementally shimmed it with small pieces of a thin plastic card until POI matched POA. This allowed me to determine the final dimensions of the P-Sight. Keep in mind that different pistols are, well, different, but the P-Sight will at least drastically improve point of impact if not put it right on point of aim at 5 yards.
