Bullet Setback A thank you to the Texas CHL forum.

By the way, why aren't you carrying hollowpoint 9's?

^^ This.......although in fairness to the OP, it might be possible that with current shortages, this is what he could find. Better ball ammo than no ammo.

One other detail: Neither of the OP's cartridges in his photo are crimped. Some "premium" self-defense cartridges are factory crimped, which helps to reduce setback. This picture of some Corbon .45 ACP +P clearly shows the crimp. This ammo is super hot, and crimping is the only responsible thing to do.

I don't know if crimping will totally eliminate setback, but it will almost certainly inhibit it.

One more thing...... Bullet setback is a good reason to occasionally fire and replace your carry ammo.

Nope, that wasn't it. This is the last thing..... Carry a gun that has some kind of loaded chamber indicator which can confirm a loaded chamber by sight and or feel without cycling the action. Examples: Springfield XDm, S&W M&P, Kahr, H&K, etc., etc., and anything with a "wheel goes round."

TAM Those Cor*Bon cartridges are not crimped what looks like a crimp is called a cannelure. It serves the same purpose as a crimp in that it stops set back. A crimp is applied to the mouth of the cartridge semi auto rounds like 9mm 40, and .45 all headspace on the case mouth so a roll crimp is not an option. When reloading for a semi auto a "taper crimp" is sometimes used to tighten the bullet to case fit and prevent setback.
