President Joe Biden spoke out against stabilizing braces during a speech, in which he erroneously claimed putting a brace on a pistol makes it more dangerous because it increases the caliber the firearm shoots. "Made it harder for people to buy stabilize braces. Put a pistol on a brace, it turns into a gun — makes it more — you can have a higher-caliber weapon, higher-caliber bullet coming out of that gun," Biden said.
