In my experience with S&W I've found their customer service second to none. If you recall S&W developed the L frame because of complaints of K frames not holding up to heavy 357 Magnum use. So I always found it strange they would chamber J framed revolvers in this calibre and expect them to hold up. The SCs are so light they are great for carry but I never had confidence in the 2 piece barrel design. A friend had a similar KABOOM with a Model 329PD in 44 Magnum.
