This device gets you in such a rhythm it isn't funny. I swear for reloading on the range this $30ish item pays for itself in what you lose reloading in range time lol.
One of the ranges here in town rents those out which is how I came across them. Bought one for myself immediately after that.
Been using one for years, and I love it. Occasionally someone will call me out as a wussy for using it, then after reloading a few dozen mags the hard way they usually ask to borrow mine.
+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!
