well I like my toys and their accessories just got a uplula mag loader for my sd 40 and wanted to do a how does it work. and after about 250 rounds it has functioned great. even got a buddy to bring me his glock mags to test and did not find any issue with his. in doing my research i found alot of it dont work or is **** plastic but after handling it and using it i would recommend it to anybody i know my thumbs thank me
