You gun takes the .38 Special. Its original (and proper) name was ".38 Smith & Wesson Special" since Smith & Wesson introduced the first gun chambered for this cartridge, which differentiated it from the earlier ".38 Smith & Wesson". The .38 S&W Special will not interhange with the .38 S&W.
You will have to call S&W
