Took my RIA XT .22 Magnum to the range a couple of weeks ago. I previously had a Keltec PMR-30 and a CMR-30. Loading the magazines was always a "bioche" with the Keltec and is with the RIA. I saw this $5.00 item ( www.magloader.com ) and decided to give it a try. All I can is, effortless. I own an Uplula for double stack mags and believe I will go ahead and get the larger size of the magloader for those. The package comes with three loaders for different sized thumbs. I was not able to try it on a Keltec but it did work well on the Ruger 10/22 25 round mags I have. Certainly worth the $5.00 plus shipping.
