Which weight is better for a subcompact handgun: 165 or 180?
I currently carry 180 Speer Gold Dots in my Glock 27, but I was thinking of switching to the 165 since it has the higher muzzle foot pounds of energy, but then I noticed that Speer only sells the "short barrel" ammo in .40. I can run physics through my head all day and come up with arguments for both round.

165 Personal Protection:
Velocity- Muzzle: 1150 50 yards: 1042 100 yards: 967
Energy- Muzzle: 484 50 yards: 398 100 yards: 342

180 Personal Protection:
Velocity- Muzzle: 1025 50 yards: 956 100 yards: 902
Energy- Muzzle: 420 50 yards: 365 100 yards: 325

180 Short Barrel:
Velocity- Muzzle: 950 50 yards: 898 100 yards: 854
Energy- Muzzle: 361 50 yards: 322 100 yards: 291
