Ecrevisse: I did try the bandaid solution at one point (medical tape, actually), and it certainly works. I like to tinker, though, and I also didn't like the idea of adding another step in the shooting prep process, however small it may be. If I get another P-10F as a backup competition gun, I plan to try the 3rd generation HBI trigger.
M1A4ME: My P-10F seems to be just as accurate as my Shadow 2. I can hold a 4" group with either one at 25 yards. I am sure they are both more accurate than I am, but I don't know the exact mechanical accuracy of either gun. Based on my performance at a recent USPSA match, I can also say that the P-10F seems to be on par with the Shadow 2 as a competition gun. I can't split quite as fast with the P-10, so I know I gave up a little bit of time there, but my overall performance was at least as good as usual.
