.22

Mr. Keys, who was carrying a pistol in his waistband, and his father-in-law tried to disarm the man, knocking him to the ground, while another relative ran back inside to get a .22 rifle.

Meza was carrying a backpack containing zip ties, a flashlight, duct tape and a .22 caliber pistol with extra rounds when he was arrested, police said.

Prosecutors alleged Ritter shot Doe three times with a .22 caliber handgun to prevent further disclosure of his relationship with a trans woman.

She also had a .22 calibre rifle, but did not fire that weapon.

At one point, Mr Pozzolo appears to have shown guests his .22 calibre mini-revolver, one of the smallest commercially available, which he has a license to own.
