Loading 9mm Glock magazines with UpLULA magazine loader. S&W Response vids OTW! *see description* 

UpLULA is a game changer if you shoot a lot through pistol magazines. Saves some serious wear and tear on your thumbs.
I shoot a Glock 19 and just today got my new S&W Response PCC setup with a Sig Romeo7s green dot. The response with big 33rd Glock mags is sublime.
To those who were counting, I wasn't paying attention and didn't totally fill the last mag.
