I went to the range today with one of my buddies, i brought my FNX and he forgot his S&W .40 so he rented the XD. When i bought the FNX a few weeks back i was deciding between it and the XD. I am so glad i got the FNX. IMHO it has better ergonomics (for my hand), better accuracy, better sights and a much better trigger.
My friend after shooting the FNX said that he was on his way to the gun shop to go buy one. He was very impressed.
So far 2 of my friends and my father in law have shot the FNX and all of them liked it a lot better than their guns (S&W .40, Beretta PX4 and a Sig P250).
I am so glad i decided on this one.
