I bought one for my wife last summer.
At first it wouldn't feed worth a $hit with anything but Stingers, and even then there was at least 2 FTF's per mag.
That was gettin pretty expensive!
Afer I swithched out the mainspring (it came with 2...) it seems to function flawlessly.
The cheap Fedral "value" pack ronds still cause the odd FTF, but they do that in every firearm I have ever fed them too.
Really the only complaint is that it is hers, and she doesn't like to share it near enough! lol
