Strange advice about "putting pretty hot 38s through it." You certainly don't need to do that. It will shoot any .38 S&W Special ammunition just fine. The original intent of chambering a heavy N-frame revolver in .38 Special was so it could handle a stout .38 Special load introduced concurrently, known as the .38-44 cartridge. That load is no longer available from the larger ammunition manufacturers, and hasn't been since the early 1970s. Dimensionally, it was identical to all other standard .38 Special cartridges, but was somewhat more heavily loaded. The "standard" loading for a .38 Special has a muzzle velocity of around 800 ft/sec. The .38-44 load produces a MV of around 1100 ft/sec. That produces a somewhat greater recoil, and the greater mass of the N-frame revolver helps tame it.

These are very desirable revolvers. Think twice about selling it. If you do decide to sell it, you will have no problem in finding a buyer. Don't be surprised if you start getting personal messages offering to buy it.
