I just got back from the range, had three mags loaded,one was the new extended
9 rd mag. Wow what a difference! It not only was longer to hold, but it felt like I could shoot for a long time, so long I had to wait till she emptied, and then realized I was out.
If it wasn't so expensive to get I would own two, though not for concealed carry.
The other thing to get used too is the mag seems like its backwards.
