I'm a big fan of my Maglula mag loaders, I have a couple in both sizes for loading mags in cold weather when numb fingers make loading more difficult, even painful.
My wife likes them a lot as they make loading so much easier for her, too.

They can be found lots of places, like amazon or top gun supply. They are designed to work with most common pistol mags.
Ooooh, I see they come in pink now!
