I second the motion for you to snatch that Ruger Security-Six-before it's too late! These are superb service revolvers and are worth every penney that you might have to pay! They are very well made(And tougher than all get out!)and will last you a very long time!
Although I eventually had acquired various revolvers from Colt and Smith & Wesson, I first fell in love with the Security-Six! These revolvers were of a very novel design whenever they first were introduced in 1971(With their simple(No tool)takedown-and, their unique, modular construction)! These guns have a long history of reliability in the field and, are proven performers! Ruger sold over one million of these fine revolvers from 1972 to 1985 when the Security-Six had been discontinued! You won't ever regret owning an Security-Six(Or, any "Six-Series" Ruger revolver-since these are mechanically the same-whether they are a Security-Six, Speed-Six, or an Service-Six)! My advice, is to go for it and never look back!
