I prefer S&W revolvers to Colt, but that is simply personal preference and has nothing to do with the reliability, accuracy, or durability of the Colt guns. I don't own one, but the King Cobra I shot was an accurate, well made gun, but I'm not crazy about stainless revolvers, and I wouldn't consider trading my M-27 for one. Don't worry about the firing pin on the Colt, you can't change the firing pin yourself on a Smith or a Ruger either. I actually like the frame size of the Colt guns, being midway between Smith's K frame, which is a bit small, and the N frame, which for a .357 is a bit large, and Colt seems to have improved the shape of the grip frame which I recall curved too far forward on my Colt Trooper. Most folks won't run into this, but I load heavy 195 gr SWCs in my M-27, and unless I trimmed the cases, and worked up another load, these were too long for the cylinder length of the King Cobra.
