I did a "lube tune" on mine, using information i learned form this forum. I also added a thrust washer to the spring guide.
I then put loc-tite on the sight screws, but mine was still shooting too high, and needed a higher front sight, so I used my dremel to drill a small hole in the front sight, and threaded in a tiny little socket head (the head is the size of the front sight) So now, I have adjustable front and rear sights. I can hit spoons at about 10 yards, which is all this pistol is good for...but its good fun plinking.
