for my pistol mags, nothing beats the uplula from maglula. I also own lula mag loaders for colt SMG, MPX and scorpion EVO mags, and they all work well.
I love my thumbs but the Uplula has made it much more comfortable and not as a pain to load the magazines while at the range as well as any other time they need to be refilled. .........And while you are at it make sure it is the bright pink one which will probably help in making the odds much greater that it or them to stay safe and not sprout legs and come up missing........................................drill sgt.
One more vote for UpLula.. ETS feels like is going to snap every time I push the plunger. Glock came as close as its Lawyers dared with the cheapie they include with their pistols... Got my first UpLula when they were $14 bucks... twice that now and still a great buy. And you only need 1.... they don't care about calibre. Well one for the bench, 1 for the go bag, 1 for the car... Get a pink one.. your wife will reward you.
