Mag Safe .45 has 12 #2 pellets, 4 #4

pellets, comprising the 103 gr bullet. The epoxy and the bullet jacket make up about half of the bullet wt. It';s a better choice than virutally any .9mm, but it's still not all that much. The 3 segment Split Nose .460, 70 grs at 2300 fps, in 4" barrels, is a lot more of what's needed.
