Locked Breech vs. Blowback

It's better for a semiauto pistol to have a locked-breech design
(rather than direct or delayed blowback), for both reliability and safety.
If the breech is not in fully-closed "battery", with the firing pin close enough to the
primer, the gun might not fire; and if it does fire without battery, that is dangerous.
A locked-breech pistol can indicate a problem before you attempt to fire.

In physical struggle with a perp, a locked breech will reduce the chance of the firing pin
moving away from the primer due to slide contact with a holster, pocket, or perp.
(shooting from a holster/pocket can save you)

A locked breech also gives the bullet more time to exit the barrel,
and for the chamber pressure to drop, before the breech opens.
A 22magnum revolver is a powerful and reliable choice for those who want simple safety.
