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.
The concern is YOUR ammo in YOUR gun. Most ammo may run fine in most guns for most users, but unless YOU have run YOUR ammo in YOUR gun to YOUR satisfaction, be wary of staking YOUR life on it. YOU do the testing, just like YOU fold YOUR parachute.
And sure, agents are not going in alone. Should “that moment” happen, it’s YOUR problem, not theirs. Felons-in-progress may not be violent in the given crime, but may fast get there when resisting getting busted.
if your job included knocking on doors in the projects to see if granny really was alive and kicking at 101 or someong else was cashing her check... would you carry a gun?
