That video is useless. He measures the subject round against another round in the box. There is normal variation in a box of ammo. And then he didn't give the measurements. Did it move 1 thousandth? 15 thousandths?
Nice pistol I like it and the price is really decent. I don't think it looks bad at all and if anything it looks kind of modern. I really like Ruger pistols and have 3 of them, a Mark, a stainless shopkeeper, and single six and they are all .22's.
