If the brush is marked .38 then it should fit. Just spray CLP all over the brush and down the barrel. Break Free is safe and effective. Later on it might be good to use a strong bore cleaner, such as Hoppe's or Shooter's Choice. If all else fails, Gun Scrubber might help. As others stated, a bore guide will avoid damage to the crown.
