I'm not a gunsmith, but experience says to give this a try first...
What Matts says.....clean and lube it each time you shoot. It might be a little dry out of the box....but I'd be more suspicious of the aftermarket mag. I was just by the gun store and they also felt that Rugers tend to be picky when it comes to aftermarket magazines.
If I'm having trouble with a gun feeding on the range, I bring a can of barrel scrubber spray and a can of air ......like the kind they sell for cleaning computer key boards. (A friend of mine swears that brake cleaner is the same thing but cheaper.) I spray it down and relube it and it usually fixes the problem. If your still having trouble with it feeding, using factory magazines, then I would take it back to where you bought it and have their gunsmith look at it.
Cheap ammo can screw with a gun......especially really old stuff. Try a box or two of good stuff, like Federal or Winchester. Good Luck.
