As the title says I'm new here, and I'd like to find the ship date for the Model 10-10 I was given by a friend. Serial is BJH7144. He bought "some" recently and believes they're turn-ins from the Michigan Dept of Corrections. This is one he's had Dura-Coated. I've read that "later" Model 10s are safe for +P+, if safe I'd like to use +P in this as it'll be my in-house gun. More handy than the AR, which will continue to be my outdoors/coyote gun. Thanks for the help!
