I think an oft overlooked Ruger design is the Security Six line of revolvers. The one piece frame on the Security Six is an innovative approach that led to a stronger frame AND much less manufacturing cost compared to a Smith & Wesson. If you've ever tinkered with a Security Six vs a Smith with the side plate you know what I'm talking about. This design concept carried forward to the Ruger GP100 as well.
