I did some search on the "web" and the consensus is that 147 in 9mm and 230 in 45 auto, with the "hydra shok" bullet are the best choice? am I GTG?

I would check out Winchester ranger T or Federal HST as carry ammo. Speer Gold Dots are gtg also...

The Second Amendment ACKNOWLEDGES our right to own and bear arms that are in common use that can be used for lawful purposes. The arms can be restricted ONLY if subject to historical analogue from the founding era or is dangerous (unsafe) AND unusual.
It's that simple.
Honestly any major name brand JHP (Jacketed Hollow Point) will work. Winchester Ranger T's, Speer Gold Dots, and Federal HSTs are my favorite ones. Shoot each and see which one is more accurate in your pistol.
I choose the heavier bullets...specifically Speer Gold Dot 147gr GDHPs.
9mm 115gr:
Velocities 1210 (muzzle) 1071 (50yds) 981 (100yds)
Energy in FP 374 (muzzle) 293 (50yds) 246 (100yds)
9mm 147gr:
Velocities 985 (muzzle) 932 (50yds) 887 (100yds)
Energy in FP 317 (muzzle) 284 (50yds) 257 (100yds)

C= the velocity of light. You're using a formula that does not apply to this topic.
Maybe you're thinking of KE = 1/2 MV^2
KE=Kinetic Energy
M=Mass
V=Velocity
Also your baseball and car analogy loses relevance in the discussion as it has the underlying false assumption that projectiles of differing weights from a handgun can be launched at the same velocity.
A 124gr 9 mm bullet travels faster (1150 ft/sec for Speer GDHP) than the 147 gr 9 mm bullet (985 ft/sec for Speer GDHP). Hence the dilemma for the shooter in ammunition selection. The 124 gr load has 47 more ft-lbs of energy at the muzzle than the 147 gr load at the muzzle and 13 more ft-lbs at 50 yds.
I'm not advocating that the effectiveness of handgun ammunition can simply be decided by a formula, but if physics is going to be introduced into the discussion, it should be factually correct.
And thus the dilemma with E=MC^2. Can it be applied in the real world? We could argue all night about it. True, it may not yield the numbers in the chart on Speer's website, but it does illustrate certain facts about bullets, expressed not in FP, but in Joules. In truth, foot-pounds is a measure of work, not energy. A heavier bullet has more energy since it is Mass x the speed of light ^2. Velocity is not used in the calculation.
The baseball/car visual illustrates perfectly Einstein's equation, and the concept of energy and transfer. We're attacking the same question from two different angles. And with that, goodnight.
