TMJ 9mm Makarov Ammo

I ran across some old ammo in 9mmm Makarov with aluminum cases and marked 95gr. TMJ bullets. I remember shooting some when I first got my Makarov to test the functioning and accuracy of my East German Mak.
I remember the ammo and gun being quite accurate and I kept the remainder of the ammo around. I am not sure what the TMJ bullets are like, but I think these might be considered "frangible" by some.
Does anyone know how these TMJ bullets perform in a self-defense situation? If they are frangible, would they act like a hollow point or do they act like the old Glaser Safety bullets?

1. The FMJ bullet still has the base of the lead core exposed, a TMJ head is usually used in match shooting and has the lead core completely encased in copper.
2. The full jacket of the TMJ or Total Metal Jacket prevents separation of the lead core with the copper jacket, preventing the lead from blowing out.
It is being used more and more as it also prevents much lead pollution as most of the lead expelled in the air by a firearm comes from vaporization of lead at the base of the bullet, which is covered by copper in the TMJ design.
I have heard of folks drilling a hole, to create a HP in these TMJ bullets. Then filling the hole with grease, to initiate expansion upon impact with these soft TMJ bullets. Don't know if it works though?

That old TMJ ammo is junk. [:0] Have heard that the powder is very dirty and there's a lot of FTFs. Send it to me for proper disposal! [:D][:D][:D]
