So i just got this gun and am curious about it. The guy told me it was a lightning but i cannot find another one with the square grips on it. I made it new grips last weekend out of maple because the fake stag ones were cracked and broken and i get bored really easy. I got it for a steal and it has MGM stamped on the frame. Its been re-nickled so the patent is lost under the nickle just wondering if anyone had any input on it. Another thing would be neat if there was a way to track if it actually came from mgm and a way to prove that it did. Everything works both single and double action. Thanks for any help!
