1. TAP-FPD (for personal defense) It's in a black box with red lettering. Widely available for purchase.
2. TAP (tactical application police) It's in a red box with black letters marked for LE use only.
They both have the same specs. TAP ammo is excellent IMO in low light situations since Hornady uses very good flash suppressants in their powders for this particular load. TAP also uses the same XTP bullet which is a proven design. I rate the TAP along the same lines as Speer Gold Dots, Federal Tactical HST's, and WInchester Ranger T-series.
Fire a round or two of say Blazer Brass and they a round or two of the Hornady stuff. Huge difference in muzzle flash. The Hornady stuff is definately some of the best out there. My PT-145 loves it by the way in both 200 and 230 grain.
