Recently I was wandering aimlessly (pun intended) through a LGS when I ran across some speedloaders. I've only been interested in revolvers for about three years but I figured what the heck, I'll get a couple. The ones I bought are specifically for GP100's. There is a disclaimer on the package saying that oversized grips may interfere with their use. I assumed that meant oversized finger grooved wood custom grips. I didn't think it applied to the rubber Hogues that came stock on the gun. Wrong. They work but it's a hassle and there's nothing speedy about it. Oh well. There's $15 down the drain. Not the end of the world but it is disappointing.
