+1 on Uplala. Guy shooting in the stall next to me asked, "Speedloader, eh. Heard they're a life saver." I replied, "It's a thumbsaver!" Wrestling that last round of .45 into the mag is a hands-down, thumbs-up win.
I'm the only one in the bunch I shoot with that has one and they all borrow it. It's awesome. My wife even asks to load my mags at home because it's so fun to use. Everyone should have one. In fact, I now what what to get for stocking stuffers this Christmas! This would even make a great raffle item at all these gun raffle/fund raisers I've been going to. Hmmm!
