Supposed to be much better through glass though.

Some other comparisons from a G22 in gel through heavy cloth:

180 Tac 1003 12.75/.66
135 PDA 1171 10/.66
165 GS 1084 12.75/.59
165 Supreme 1096 13.5/.60
155 Silvertip 1152 15/.57
155 Gold Dot 1153 14/.61

FBI puts a premium on tactical barrier penetration, retained weight. For latest contract ammo they solicited ammo from 160-180 grains, and when all the testing was done the Speer 165 Gold Dot was the new duty ammo.

The tactical rounds are designed with a very soft pure lead core and the core is soldered/melted to the jacket to bind them together this is a different process than the manufacture of a gold dot bullet and the tactical is not as "tough" as the GD.

The Tactical does however have the highest measured bullet performance against laminated and thermo pane glass.

Upon striking the glass surface the tactical bullet with it's very soft core suffers massive deformation that allows it to conform to the angle that it was fired at.

This conformation or bending to the surface shape this allows it to continue to penetrate the surface without being deflected or "skidding" or bouncing off of the surface.

This construction process does cause the Tactical to suffer from reduced expansion and somewhat reduced performance in standard and clothing obstructed gelatin testing.
