The factory Ruger 25s work fine for me, George, but they're damn pricey. Ruger also makes a mag with two 25s built as a single mag. Those double 25s are usually $50 anywhere you look, but I did find a place online that had 'em on sale for $35. Snapped up a couple at that price. If you're focusing on accuracy, stick with the lighter Ruger 10s. Be wary of buying non-factory brands, a lot of 'em are crap.
