I've had mine for 2 days, last night I loaded and unloaded a magazine for my new m&p45 about a hundred times playing with it. It works great for the 3 types of pistol magazine I have: m&p40, m&p45, and Ruger P93DC 9mm. I did not try it on my LCP magazines since it is supposed to require the baby Lula like all the other little pocket autos.
