After much research, and now that I own one, usage and thinking about the Philosophy of Use (I know some of you guys hate the man who uses that phrase, but I digress), I have come to the conclusion that the FNP .45 Tactical is the firearm component of an extremely versatile Offensive Handgun Weapon System. Ok this is the part where the overused and often incorrect cliche is used...(A handgun is not offensive). Actually depending on the "mission" and configuration of of the firearm, a handgun CAN be an offensive weapon.
I say weapon system because the actual handgun is just a component (albeit the major component) of the entire system. To make it into an Offensive Handgun System, we can add a MRDS to the slide, a light and laser combo on the rails, already comes with 3 hi-cap mags, is a powerful caliber (not THE most powerful, but perfect balance of size, manageable recoil, muzzle energy, controlability), and a threaded barrel for a suppressor or flash hider. Not to mention small things like ambi-controls, tall tritium night sights, and a field case that can store and transport all of the components.
With the mini red-dot sight you have quick target acquisition ability in daylight/lighted conditions, or in low light when you wouldn't want to give away your position like a laser might. With the white light/laser combo you have illumination capability in ultra low light/no light conditions, and the ability to mark and take down targets with pinpoint accuracy (within reasonable distance) wit the laser. The tall night sights provide a co-witnessed backup option should your optics malfunction OR if you just prefer irons, plus their high profile will prevent sight picture obstruction with a suppressor attached. Tritium charged "dots" helps to mitigate potential low light targeting issues. Adding a suppressor helps muffle the report, while also significantly reducing muzzle flash which helps the operator as far as eyes adjusting to the flash in low light conditions, and to boot it can have a positive impact on recoil. The high capacity magazines allows an operator to have more rounds should he need it...which plays a major factor in an offensive role.
I feel the offensive role most suited for a weapon system like the Tactical .45 would be in an assault team primarily in an interior situation (think office buildings, or drug house seizures) WITH long gun or submachine gun support. Now if we are talking longer distance engagements, or very large open interiors like an airport for example then it would not be ideal.
