Since almost 70% of U.S law enforcement and now all of the U.S. military have transitioned to striker-fired service pistols, I don’t see what the argument is for civilians to not carry striker fired pistols. It’s common sense & logic to train & practice with whatever you choose to shoot and carry to maintain safe proficiency with the firearm. A 1911 is a firearms enthusiast’s choice to own & carry, well a lot of military and law enforcement are not firearms enthusiasts, it’s not part of the job description. The 1911 and the M9 were both phased out of military use for reasons that enthusiasts don’t accept, but which are well documented, even if you don’t like it. I know plenty of cops who don’t necessarily like what they are forced by regulation to carry. But they qualify with them with no problems and accept that they have to carry Glocks. I know most of them have better things to worry about, such as staying safe on the streets. And I don’t know any cops who quit the force when they were requited to carry Glocks, although a lot of old-timers carped like crazy about it. And a lot of combat veterans don’t pick up a firearm or shoot another round after they leave the service, it happens all the time.
