Wrong about the .22lr. Never said that it cannot.
Really? So if .22lr can kill a bear, why not going out into the woods armed with that?
Wrong on the SAMMI. Almost every new pistol can. Just the fact that you don’t know that speaks volumes.
Have you actually read the factory literature for "most" modern pistols? Because unless there is documentation which explicitly states a +P rating, the firearm is in fact NOT rated for that cartridge.
