I love mine.... It is a "Classic" with the full under-lug. It's my "work horse" hunting gun and it has served me well. The convertible front sight blade is a wonderful feature for different sighting conditions.....
There are many negative conceptions floating around about the latest 629 models (all new S&W's for that matter) and I've found nothing so far to support any of those assertions.
The N frame 5" guns have always been my favorite barrel length, and as many others have found, it has the best balance of any S&W handgun. I own many S&W 44 Mags and I've gotta say the 629 Classic is the most accurate of my shooters...
JMHO...
