If you’re serious and have the money to do it (or, well, somebody else’s money), you train with what you carry - and you carry what you’re willing to stake your life on. Getting shot at by a high-stakes felon-in-progress is not when you want to discover that your department-issued sidearm doesn’t like “ashtray” JHPs all the time, refusing to cycle on 5% of ‘em.
Yes, I’ve burned thru 2000+ rounds of JHP in one week of training before. Still would if I could afford it. SSA can afford it.
You are still affording it, albeit indirectly through taxes.
If your ammo doesn't cycle your issue 5% of the time, why would they buy the junk ammo to begin with? Were they too stupid to test it before purchase?
SSA felony in progress is on the level of FRAUD, not a hell of a whole lot of violent crime in progress to begin with, so having a major shoot out sit likely.
Busting a major SSA fraud ring, they aren't going in alone anyway. They will have FBI or Marshall with them.
