Uplula and maglula are there similar others? Is the squeezing hand type a better choice than a push down type like the raeind? TIA

I like Lulas because they make unloading such a breeze. In my hands they're quicker than the tray-type (Cammenga) loaders. Much depends on how much you practice loading mags. Eg., I'm fastest with Uzi mags using just a bit of thumb pressure and tapping the base on a solid table.

Uzi mags are heavy gauge steel, tho. So it depends on the mag design and materials.

I bought a Caldwell squeeze type, supposed to work with multiple different mags., and it is disappointing. My Ruger 1911 9mm mags. are about the hardest to load magazines I have encountered and this tool just doesn't get it done. I ended up building my own.
