About the DA pull in S&W revolvers... it's the result of a stronger hammer spring. It's not to make you think before you pull the trigger - it's added hammer strike will ensure that the primer goes off even in a less than pristine firearm. I leave my CCW springs alone, but have changed my others to Wolff reduced power springs, as my reloads all use Federal primers - and have had no ftf's due to insufficient fp hit. My only 'dud' has been the two rounds I didn't put powder in!
I loved my first JM 5" PC627 V-Comp - best trigger I ever had in a handgun - that was a fine example of the PC Shop's work. Horrible front sight - and no replacement HiViz front sights would fit. I bought the first 4" 627 Pro I found locally (5/08 - $719). It displaced the V-Comp! It was like my early 625JM, the first of the 'Pro' series, in that it's tool-less front sight replacement actually required the same height HiViz sight. That, and it's VG+ stock DA trigger made it a winner - for nearly two years - until S&W ruined the used market on the UDR 2 5/8" PC627 by re-releasing them. My first one, bought 4/10 for $949, was followed six months later by a second one ($889), funded by the sale of my 5" JM PC627 V-Comp. I love the UDR! The second one was left stock as a night table HD firearm, while the re-sprung first purchase is a fun gun. I love their big red ramp - it's far easier to see in dim light than both a HiViz and my Tritium Night Sight (Governor & 3" 60 Pro came with them!). The first UDR came with it's front sight to one edge of the dovetail while both came with equally poorly-fitted Eagle wood grips, which I replaced anyway with some PC shop grips (See below!). My favorite S&W has to be my first - a 4" 625MG in .45 Colt - but the UDR is a close second.
