Same here, I had a few cheap Range Tray loaders for the 9mm/40 and the .45 Shield. That's all that was needed to get that last round in when the mags were new.My 45 Shield mags were a lead up to injury until I got a 10$ orange plastic loader off ebay. I keep them full constantly and in just a few weeks they mellowed out to where I don't use the device any longer. I don't even know were it is now.
Now that the mags have had some use, I don't need the loading tools anymore.
(Until I buy some more new mags or a new gun !)
