kicks butt out of the box

This is a good mag for the cz40b it only says cz40 but it is meant for the cz40b base plate and all. I think it is factory but I could be wrong. When i got it it was a little hard to get the last two rounds in, so once I finally did, I left them there over night, then took it shooting. Rounds fed in with no problem at all which leads me the think that it is, in fact, a factory mag.
