Well I will give it a shot,
First I like my 45ACP's to be a 230 grain bullet.
I don't see the need for +P in 45 (9mm OK but 45 will never be a speed demon) it shoots OK from the Glock 21 but is very robust from the 30 and 36.
Federal HST would be a top choice for me.
Ranger T or SXT would be another high choice.
I would make it my goal to get some of the LEO only ammo in either HSt or Ranger.
My friend who is a big 1911 guy shoots Remington golden saber the best and swears by them.
And Gold Dot is tried and true.
Never been a fan of frangible ammo expecially in a big slow moving slug of lead like a 45. You would want it to stay together a be a big slab of lead.
