So I know absolutely nothing about revolvers. Hell, Ive never even shot one. However, I was given this gun for FREE today. I was told it’s an antique, but nothing else is known about it. I can see it’s a S&W and it’s chambered in .38Special…. The trigger functions and hammer drops what I feel to be smoothly. The gun opens up as it should. I was told the last time it was fired was 1950’s or so. What can you more educated guru’s on the subject teach me
