The FNP is a GREAT shooter. It will eat every type of ammo you can feed it and not even blink. It comes with 3 magazines which its plenty for a beginner shooter and even the advanced shooter! I was hesitant when I bought mine because I had never handled it before but
Its a great pistol, especially for a women. My girlfriend always complain about how some of my pistols kicked and she would only put a very limited amount down range before it start it hurt her wrists. She has made my FNP "her" gun.
She could shoot 500 rounds in one range visit and not worry about fatigue or wrist pain. Its the first pistol she reaches for when we go shooting.
You definitely cant go wrong with the FNP but there are some other good choices out there as well. I have been considering the S&W M&P9, Sig 228, Ruger SR9/SR9c, S&W 3913 or the budget line, and last but not least the Bersa Thunder 9 and 9 compact variety. All theses I have mentioned had been in my sights for a while. I owned a 228 and loved it but it was a a tad on the heavy side (26 oz empty) for my girlfriend.
The M&P9 or 9c are definitely in my future. I have heard nothing but good reviews out there and they have plenty of upgrades available already. They also come in at a great price:
M&P9 $449 The S&W 3913 are great shooters and I recently almost pulled the trigger on one but they were just to hard to find and a little pricey. THe budget line are also great pistols. Look at the 908s. They are very similar to the famous 3913 but just dont include all the fancy extras like ambi safety.
Anyways good luck and hope this helped! Also post pictures of whatever you get!
