I have a S&W 27 that I purchased used; the old ones are really well made and it shoots like a dream. My newest SMith is about 10 years old; I fired a S&W 686 the other week and jerked the trigger on the first pull since the trigger has about 2 1/2 lbs on my older ones. That being said, I like the new 4.2" 686's and a trigger job would solve the only problem I saw.
