Ok, I was just giving an example of how it's possible to get rust after it left the factory.
I agree that guns should work from the factory,,, but the tolerances QC accepts may be larger than what some shooters expect.
We've had these discussions before here,, and we'll have them again. Ruger is in the business to sell a product. They, like any company want to sell a lot,, without losing much. All to often in ANY manufacturing process,,, a product gets passed that is marginal,,, hoping it'll get sold & not get noticed by somebody. Line workers have production numbers to meet,,, scrap or bad parts cost time & money,, and a lot of workers let a lot of things slide by. No matter what the company is making.
HOWEVER,,, a gun shop that gets in a gun,, and DOESN'T inspect it for such obvious flaws such as rust,,, or extremely rough areas such as mentioned above, and puts it out for sale is also wrong in hoping a buyer will buy it & go about their business. Gun shops can inspect a gun easier & quicker & take any "bad" guns and have them sent back a lot easier than pissing off a customer.
Yet,,, when a problem is noticed,,, and politely brought to Ruger's attention,, they happily fix it. Remember,, they are human,, and mistakes do happen. But,,, all too often some folks expect the quality of a Freedom Arms gun for the price of a Ruger. Production vs custom... check the costs!
