I recently acquired a model 36 no dash which I have been advised was manufactured in 1963. It is in good mechanical condition and I have shot about 100 rounds of standard pressure 158 grain fmj through it. Could any of you tell me if it would be okay to load and occasionally fire plus p .38 special through it? Specifically, I have Winchester white box sjhp 125 grain + p and Speer gold dot jacketed hp 158 grain +p. I would only shoot about one or two cylinder fulls per range session every few months and carry it loaded for self defense purposes with two speed strip reloads. Thank you in advance for your feed back.
