mikegs430 is correct. It was made in '79. I see a lot of people ask about dates on here. Even though most can be researched online, post '80 serials cannot, well I shouldn't say cannot as the colt website sometimes pops newer ones up but a lot of the time (when it counts) they don't return an answer. I would recommend that anyone really interested pick up the two pocket manual books for Colts. The date book and the value book. I went to abebooks dotcom and paid $25 for both and that included the shipping. I love them. I also have digital copies of the Jerry K. repair manuals, the 1st vol, 2nd vol, and the 1911 repair manual. They are in pdf. If anybody needs some info out of them PM me.
