Who wants to load 1 round at a time when Rapidfiretek is all aluminum and you can shove in up to a full 30 at once.
Edit*
On second thought, I'll probably get both. I ordered the rapidfire a couple days ago so it's not on hand yet but I can already tell it's not carry-around with you friendly. But when all 5 mags are empty at a time "even more mags when I buy some manticore's once avail" using speed loaders sure as heck beats loading 150rnds by hand especially when they are getting sheet metal feed lips in the aftermarket.
