I have the FNP .45 and really like it. They are basicly the same gun. I have not put many rounds through mine yet (maybe 200) but have not had any issues with it. The gun shoots well and is accurate. It is hard to beat 15 rounds of .45 and I love how you can carry cocked in locked like a 1911 or you can de-cock it like a beretta or sig. Also I like how it comes with a different backstrap so you can change it to fit you.
For years I wanted an H&K USP but they are just so pricey! But then I discoverd the FN and seen it has all the features of the HK but cost less and was made in America! So I basicly bought this gun to be my HK, and turns out I think I like it more than the HKs I have shot! Shoot mine even came with tritium night sights!
Needless yo say I think you will be happy with your purchase! Congrats and happy and safe shooting!
