My new black FNX45Tactical arrived today, have not fired it yet but I did do a thorough detail comparison to my FDE FNP45Tactical (sorry no pictures). One is black and one is FDE. One has FNX Tactical on left side of frame, the other FNP Tactical...
Besides the color, the external looks and appearance are virtually the same and both will fit in the same holsters. To someone not very familiar with either, would say they are the same, but they aren't! The grip angle and bore axis height are the same. The X barrel is fully supported while the P is not. The X barrel will drop into the P frame but NOT vice versa. The hole in the front of the X slide is slightly smaller in diameter and the P barrel will not fit in it! However, the complete P upper assembly fit on the X and appeared to be OK, but I would not fire it this way, just wanted to see that the frame rails etc. were the same.
The frame on the X under the left and right slide locks are shaped slightly different than the P.
The recoil spring is stiff and has 27 coils versus the 32 coil modified spring in my P.
The trigger pin is different, the X has has a small dimple on the left side end, the P doesn't.
Now for the Mags- they are completely different! The X body is about 13 thousands of an inch longer in the front to back dimension than the P. The followers are completely different and not interchangable as the X mag body is shaped differently at the top to fit the new follower. The X has a 10 coil mag spring and looks a different color and/or material than my 11 coil P springs. The bottom rounded floor plates look the same although the X has a "1" molded on the inside; (didn't try to interchange them) The X body has 12 witness holes from 4 to 15. The P has three witness holes at 5/10/15 levels.
The P mag will fit loosely in the X frame and does lock in. The X mag will fit tightly in the P frame and does lock up but will not drop free. I do not plan to try and fire the Xin P and Pin X!
My conclusion is that I plan to treat the X and P as completely different pistols and not interchange any parts. now if I can find any X mags?
That's the differences I could find for now, thought some of you, like me , would want to know. Hope to get it to the range soon!
