I bought a 642 but hesitate to recommend it due to the trigger pull. I 'm also very curious on the subject and am following closely. Perhaps I should take a look at the Wilson spring kit. At that price, what's to lose?I have both. I like the 642 better. Replaced the Trigger spring with a Wilson Combat S&W J frame Custom Tune Spring Kit. $8.95. Easy to replace the spring. Much improved trigger. Full disclosure: I'm a S&W revolver junkie.
Great point...I didn't even think of the Smith & Wesson 340!Or just buy a 340. The 340 is basically the 360 without the hammer. I am a big fan of my 360J in .38+P...it's my working-out and dress-clothes gun. It's lightweight, accurate, and disappears in a pocket. Personally, I like the exposed hammer, but if the OP is looking for hammerless, the 340 is the way to go.
