I have both an MD 40 (.40 cal) and a Star Firestar Plus (9mm). I love them both.
The MD 40, which is nickel, is heavy, but small and accurate. The Firestar Plus, which has an alloy frame, is much lighter, has a double-stack magazine.
Both are single-action only, both have good triggers (the .40 has been worked on) and both are great carry guns. The 9mm is my concealed carry weapon. About the same size as the Kel-Tec P-11 (a little larger and about 7 oz. heavier) but easier to shoot well, and very, very accurate.
(I have a bunch of other handguns, including some high dollar ones, but these are among my favorites.)
