The Smith & Wesson 629 CLASSIC is basically a modern version of the original Model 29. My CLASSIC is a 6.5" barrel with the "POWER PORT" located in front of the front sight. This is to reduce muzzle rise. This version utilizes the latest upgrades while keeping the old "traditional" look. Personally I really like this look.
The downside to the 629 CLASSIC is, it still can't handle any Monster Killer Ammo like BUFFALO BORE 305 grain, +P+ 44 Magnums. However, it can handle all other 44 Mag ammo with the best of them.
