Maybe for you. I have only one hand and it makes it easier for me. I had learned how to rack a semi auto with one hand, but a guy showed me one. I tried it. I liked it. I bought it.
Sorry about your hand.
Unlike you, most all folks who carry a defensive weapon must choose to either carry it with a unit in the chamber or risk not having two hands free to do so. Two hands free is an unacceptable choice. Hence my comment. I have no problem with a chambered round. I was addressing my comments only to those who have some reason not to carry with a round in the chamber.
