Thanks Hollander! I checked it out on YouTube and it looks like it pretty much works on almost any pistol mag. According to Magpula's website there are a few that it doesn't work on but won't affect anything I own. I know folks are saying that the XDs mags are easy to load but I have a hell of a time getting that last round in.
The Wanamaucher's gun show is here in Tulsa 11/10 & 11/11 so I'm going to look for one there. They claim to be the largest gun show in the U.S. and I believe it. I bet at any given time during the show there are at least 10k people in that building. :-)
