I have to disagree with you here.
Each individual cartridge is an integral part of the operating mechanism of a semi-automatic pistol. It is the height of foolishness to train/practice with a different type of ammunition than you will carry.
Back in the olden days when LE had revolvers, it was reasonable to practice/train with less expensive non-hollowpoint ammunition of the same bullet weight and velocity as used in service.
Good points ...
“It is the height of foolishness to train/practice with a different type of ammunition than you will carry.”
That is BS. Yes, make sure the rounds feed well in your gun, but practice constantly with hollow points? LOL! In the adrenaline-filled rush of an actual scenario, at the close range such battles take place in, almost every other factor so far outweighs the minute differences between rounds that it is negligible.
The basics of keeping the gun running, stance, presentation, grip, sight focus, trigger control, shot placement, basic tactics and such are the real key to survival, and can, indeed, be honed for the most part even through regular dry fire practice.
Fools who waste the taxpayers’ dollars practicing extensively with hollow points “just because they can” (ie, don’t have to pay for it) are no more likely to prevail in a gun battle than anyone else. Indeed, I believe the accuracy statistics on the typical inner city criminal who uses simple “point and shoot” technique just about match LEOs in the same gun battles.
