They need a gun with a longer barrel and a higher caliber.
Changing any variable like that could change the outcome of the fight, and not necessarily in favor of the women.
A larger gun may have resulted in slower response & firing time, more misses and therefore possible injury or death to one or both women which did not happen with the guns they used which in hindsight, did not happen with the weapons they used.
Obviously they both could have died as it was but...
Statistically, the best gun for self-defense is a 9 mil. They have laser light attachments that give you one shot one kill ability at close range. A Glock weighing 2.1 pounds has been endorsed by Navy Seals. It has a short barrel.

Though I've thankfully never been in a close quarter shoot out (or for that matter, even a long range one), can one watch the one above unfold and suggest that laser sighting would have been any help at all?
Everything happens too damn fast to even think, much less line up a laser on a moving target right in front of you. The extra half second one takes to do that may be longer than one's life expectancy.
Training and practice with a weapon that fits well in your hand grants the best advantage, I'd wager, more than laser sighting or weapon caliber.
