Lucky Gunner tested their .45 ACP loads out of a Kahr CW45 that has a 3.64" barrel. Gold Dot results were:
230 Gold Dot-752 fps.,expanded to .71 caliber with 12.9"of penetration.
230 Gold Dot Short Barrel-806 fps, expanded to .70 caliber with 14.4" of penetration.
For comparison... 200 gr. Gold Dot +P - 982 fps., .70 caliber and 13.8" of penetration.
185 grain Gold Dot - 964 fps. ,.70 caliber, and 14.1" of expansion.

Doesn't seem to be a whole lot of difference between the 4 loads as far as performance.

The Gold Dots, along with HSTs and Ranger T's seem to be very consistent across the board, more so than any other brand or type of bullets.
