When I said no such thing as a "bad" ruger MK, I meant the different generations and variations. Not that every single MK ever made was perfect. Every gunmaker, no matter how good their reputation, puts out at least a few lemons every now and then. Id be willing to bet if your buddy would just send the gun back to ruger like you said, they would make it right. If its as bad as you say, I wouldnt have wasted my time putting more than 500 rounds through it. After a hundred rounds or so each from a few different brands it should be obvious something needs to be fixed, cause that surely isnt the norm for that gun.
