Actually by that definition, almost all hollow-point rounds are frangible. The
prefragmented round/ frangible slug is a round that holds small pellets in a
hard gel. Upon hitting they break, transfering almost all of their energy to
the target. Cor-bon makes a round called Bee-safe that is that exact thing.
The standard round is a hollow-point, lead incased in a copper jacket, the
panels are to aid expansion of the round. Federal, Winchester, Remington all
make hollow-points based ont eh same principle, with differeng make-ups
(federal with the little pin etc. Different powders and such)

You are talking specifically about the Glaser Safety slug and various
copies. Clearly, that's not the only way to make a frangible round.

And, BTW, Glasers are rather expensive ($24 for a box of 6) whereas Cor
Bons are a bit cheaper ( $20 for a box of 20) and more effective (although
they penetrate more than the Glaser or Mag-Safe, which is a bad thing in a
house).

I am just saying that as I understand it a frangible slug, is the pre-
fragmented round, by your definition, it includes standard hollowpoints.
Glaser is a prefrag, Cor-bon is a hollowpoint. So I will drop the word
"frangible" since that seems to be a point of contention :-)

Glasers have come down a lot (they seem to have been passed by) sticking to
the 9MM, they run around 13$ for the 6, Magsafe around 18-28 for 6, while Bee-
safe is 18+ for 8rounds.
Prefrags have the advantage of better stopping power, since they transfer
their energy better (or rather more-fully) They do not penetrate through as
many walls.
Hollow-points expand to cover more surface area, passing more energy to the
target, but can still blow through or over-penetrate. With any round going
through the body, some of the energy is not transfered. They also will go
through more walls than a prefrag, but less than a FMJ.
