I have a Mini in the 183 series serial number, I have had it for 30 years and have decided to do some upgrades, I looked on the Ruger web site and believe it is a 1982 model, I am looking at the Archangel but do not know if it will fit my Mini do to the ejection of the brass, what stock options are out ther for my Mini, I am new to the forum, wish I had found it years ago!!!
