Ruger P95. Amazingly accurate, no recoil. Its the first gun I ever owned that would put the bullet right where it is supposed to go, over and over again, all day long. It never malfunctions, and will digest any ammo, including that down and dirty steel crap.
Honorable mention goes to my two 9mm revolvers, a Taurus 905, and a Charter Arms 9mm Pitbull. I took a chance on the 905, as I had never owned a Taurus before. There weren't any other 9mm revolvers available at that time, and I really wanted a rimless revolver. Its been an excellent little shooter.
My Charter Arms 9mm Pitbull has been a little quirky, but once I figured out what it likes, its a joy. Extraction of fired casings was its issue. It only likes brass ammo, and if I feed it as such, its perfectly reliable.
