Well, as I familiarize myself with these forums, I keep thinking "Oh yeah? I bet someone on DP could ID this!" So into my box of strangess I delved. This came up 1st.
As always, any help is appreciated! I tried the net, of course, but try Googling 'Colt light gun' and see how many firearms you get! Obviously 1st Gen, what system is it for? Oh, it has a round, 3 post connector, if that helps.
